## What Is The Term Used To Describe The Rate Of An Object’s Movement??

**Speed** is a description of how fast an object moves velocity is how fast and in what direction it moves.

## What is the term used to describe the rate of an objects movement?

**Velocity**. When you know both the speed and direction of an object’s motion you know the velocity of the. object. Speed in a given direction is called velocity.

## Which term best describes a change in an object’s motion?

**acceleration**. occur all around you as objects speed up slow down or change direction. changing direction. a change in velocity can be either a change in how fast something is moving or change in the direction of movement.

## What is the term for the rate at which an object is moving at a given instant in time?

**Instantaneous speed** is the rate at which an object is moving at a given instant in time. When you know both the speed and distance of an object’s motion you know the velocity of the object.

## What is the rate of change in an object’s position?

**The velocity** of an object is the rate of change of its position with respect to time. The speed of an object is the magnitude of its velocity.

## Which refers to the rate of change in velocity quizlet?

**Acceleration** is the rate of change in an object’s velocity.

## What is the rate of motion of an object?

**Velocity** is a vector quantity that is defined as the rate of change of position of an object with respect to a frame of reference with respect to time. Velocity is equivalent to the speed of the object along with the direction of motion.

## Which of the following terms describes an object’s resistance to a change in motion?

**Inertia** is the resistance of any physical object to any change in its velocity. This includes changes to the object’s speed or direction of motion.

## How can you best describe an object’s motion?

You can describe the motion of an object by **its position speed direction and acceleration**. An object is moving if its position relative to a fixed point is changing.

## What is the rate of change of velocity is called?

**Acceleration** is defined as the rate of change of velocity. Velocity is a vector which means it contains a magnitude (a numerical value) and a direction.

## What is motion used to describe?

In physics motion is **the phenomenon in which an object changes its position**. Motion is mathematically described in terms of displacement distance velocity acceleration speed and time.

## What refers to the measure of how fast an object move?

**Speed** is a scalar quantity that refers to “how fast an object is moving.” Speed can be thought of as the rate at which an object covers distance.

## What is the rate at which an object changes its velocity?

The velocity is changing over the course of time. In fact the velocity is changing by a constant amount – **10 m/s – in each second of time**. Anytime an object’s velocity is changing the object is said to be accelerating it has an acceleration.

## How do you find the rate of change in a position?

## What changes an object’s motion?

The motion of an object is determined by the **sum of the forces acting on it** if the total force on the object is not zero its motion will change. The greater the mass of the object the greater the force needed to achieve the same change in motion. For any given object a larger force causes a larger change in motion.

## What describes a change in velocity?

**Acceleration** is a measure of the change in velocity of a moving object. It measures the rate at which velocity changes. … People commonly think of acceleration as an increase in speed but a decrease in speed is also acceleration. In this case acceleration is negative and called deceleration.

## What is velocity quizlet?

Velocity. **Measure of distance traveled in a given period of time with a direction**. Constant velocity.

## What refers to the motion of an object moving in a straight line?

**Linear motion also called rectilinear motion** is one-dimensional motion along a straight line and can therefore be described mathematically using only one spatial dimension.

## What is the technical term used for the rate of motion of a body?

**speed or velocity** is the technical term used for the rate of motion of a body.. it’s unit is m/s & km/hr.

## What is meant by rate in physics?

In physics rate means **rate of change**. Basically how much a certain quantity changes with respect to another quantity that is also changing. You may also sometimes hear the term gradient which describes the same thing. And mathematically it is also a ratio say for example.

## What is resistance to change called?

This is a phenomenon called **structural inertia**. Groups teams departments or leadership may resist change due to this form of inertia. … When customers clients or other external stakeholders resist change they are taking part in external resistance.

## What term is best defined as an object’s tendency to not change its motion?

**Inertia** is the tendency of an object to resist changes in its state of motion. … The state of motion of an object is defined by its velocity – the speed with a direction.

## What measures the resistance to a change in the object’s motion?

**Mass** as a Measure of the Amount of Inertia

All objects resist changes in their state of motion. … The more inertia that an object has the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

## How do you describe the motion of a graph?

If an object moves along a straight line the distance **travelled** can be represented by a distance-time graph. In a distance-time graph the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

## What do motion graphs tell?

**the rate of change of the variable on the vertical axis**so we can understand velocity as the slope of the position vs. time graph.

## How do you describe motion in physics?

motion in physics **change with time of the position or orientation of a body**. Motion along a line or a curve is called translation. … In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

## What is rate of change of momentum called?

The rate of change of momentum is called **Impulse of force**.

## Is the rate of change of velocity *?

**Acceleration**: The rate of change of velocity is called the acceleration of the body. Acceleration is also a vector quantity.

## What is the term for the rate of decrease of velocity of a body?

Acceleration is the rate of change of velocity with time. … Any change in the velocity of an object results in an acceleration: increasing speed (what people usually mean when they say acceleration) decreasing speed (also called **deceleration or retardation** ) or changing direction (called centripetal acceleration ).

## What is velocity and how is it useful for describing an object’s motion?

Velocity describes **motion by indicating how fastan object moves and in what direction**. Speed is a magnitude of velocity which indicates only how fast an object moves. Speed shows how much distance is traversed in a given interval of time: In a general case of motion …

## What is an object’s speed a measure of?

Speed is the rate at which an object’s position changes measured in **meters per second**. For example if an object starts at the origin and then moves three meters in three seconds its speed is one meter per second.

## How can a graph help you understand an object’s motion?

Summary: A **speed – time** graph shows us how the speed of a moving object changes with time. The steeper the graph the greater the acceleration. A horizontal line means the object is moving at a constant speed. A downward sloping line means the object is slowing down.

## What is speed measurement?

Speed is a measure of how fast something is travelling. The speed of an object is how far the object travels in one unit of time. The formula for speed is: **speed = distance time**. The most common units of speed are metres per second (m/s) kilometres per hour (km/h) and miles per hour (mph).

## What term refers to a fixed place or object used to determine the position of an object?

Answer: C) **reference point**. Explanation: the term refers to a fixed place or object used to determine the position of an object is reference point.
