# What is a background or object that is compared to a moving object?

## What is a background or object that is compared to a moving object?

Frame of Reference. The background or object that is used for comparison of motion.

### What background is used to compare motion?

The none-moving object or background used for comparison is the frame of reference. The most common frame of reference is the earth or the ground. 5. Relative Motion: Movement is relative to a particular frame of reference.

#### How do you describe the motion of an object?

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. Even things that appear to be at rest move.

What do we call the point you use to determine if an object is moving?

A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving.

What is motion describe?

motion, in physics, change with time of the position or orientation of a body. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity). The most general kind of motion combines both translation and rotation.

## 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.

### How do you describe the position of a person or an object in relation to a reference point?

An object is located relative to a reference object. The description of an object’s position changes from one reference point to another. (An object or point can be located from two know points with a distance and direction from one point and either a distance or a direction from the second point.)

#### What is meant by the term reference body?

in physics, motion is observed when an object changes its position. To help that, a body of reference is given . eg. a car started from that tree and travelled x km. so tree is the reference body here.

What is meaning of describing motion?

Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. So, the term motion, in general, signifies a continuous change in the positions or configuration of a physical system in space.

What does it mean when motion is described as relative?

What does it mean when motion is described as relative? It means that motion of any object is described relative to the motion of any other object. It means that motion is independent of the frame of reference. It means that motion depends on the frame of reference selected.

## 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).

### How do we describe motion quizlet?

How can you tell whether or not an object is in motion? Compare its position to that of a reference point. If the distance or direction to the reference point changes, it is in motion.

#### When do you say that an object is moving?

An object is moving if its position relative to a fixed point is changing. 4.1 Motion Is Relative 4 Linear Motion Even things that appear to be at rest move. When we describe the motion of one object with respect to another, we say that the object is moving

What does it mean when an object changes its position?

A change in an object’s position tells you that motion took place, but it does not tell you how quickly the object changed position. The speed of a moving object is a measure of how quickly or slowly the object changes position. A faster object moves farther than a slower moving object would in the same amount of time.

When do you need to describe the position of an object?

More precisely, you need to specify its position relative to a convenient reference frame. Earth is often used as a reference frame, and we often describe the position of an object as it relates to stationary objects in that reference frame.

## How can you tell if an object is in motion?

If you were to watch her jump, you would see that she is in motion. is the change of position over time. As she jumps, both her horizontal and vertical positions change. If you missed the motion of the jump, you would still know that motion occurred because of the distance between her starting and ending positions.
