Amplify: Forces & Motion Study Guide

Front

What is speed?

Back

Speed is how fast an object is moving.

Front

What two factors does the motion of an object depend on?

Back

The motion of an object depends on the mass of the object and the amount of force used.

Front

What is mass?

Back

The amount of matter in an object is called its mass.

Front

What is velocity?

Back

Velocity is speed in a particular direction.

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
