Force and Motion Study Guide

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the force that pulls us toward the Earth.

Front

What is friction?

Back

A force that opposes the motion of an object when it comes into contact with another surface.

Front

How does mass affect motion?

Back

Objects with more mass require more force to move the same distance as lighter objects.

Front

What happens when equal forces are applied to two objects?

Back

The motion of the objects will depend on their mass and the friction acting on them.

Front

What is the relationship between force and acceleration?

Back

The greater the force applied to an object, the greater its acceleration will be.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How can you increase the speed of an object?

Back

By applying a greater force to it.

Front

What is the effect of surface type on motion?

Back

Different surfaces create different amounts of friction, affecting how far an object can move.
