Unit 2 - Motion Review #2

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How do you calculate distance when speed and time are known?

Back

Distance = Speed × Time.

Front

If Michael walked at 2 m/s for 3 minutes, how far did he walk?

Back

360 m.

Front

What does gravitational potential energy depend on?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

If Shona cycles at an average speed of 8 km/h for 4 hours, how far has she travelled?

Back

32 km.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy = 1/2 × mass × velocity².

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is the formula for gravitational potential energy?

Back

Gravitational Potential Energy = mass × gravity × height.
