Amplify: Forces & Motion 1-2

Front

What is speed?

Back

Speed is how fast an object is moving.

Front

What is a force?

Back

A push or pull that can cause motion.

Front

What happens when you exert a stronger force on an object?

Back

You will see a greater change in velocity.

Front

If the same strength force is exerted on two objects, what will happen to the object with more mass?

Back

It will have a smaller change in velocity.

Front

In which direction must a force act to stop an object?

Back

The opposite direction as the object's motion.

Front

What is velocity?

Back

Velocity is speed in a particular direction.

Front

What is the relationship between mass and acceleration when a force is applied?

Back

More mass results in less acceleration for the same force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does friction affect motion?

Back

Friction opposes motion and can slow down or stop moving objects.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
