Unit 5 Test - Energy

Front

Power is proportional to _________.

Back

work

Front

Gravitational Potential Energy is directly proportional to

Back

weight and height

Front

The type of energy an object has due to its motion is ___________.

Back

Kinetic Energy

Front

An arrow in a bow has 30 J of potential energy. Assuming no loss of energy, how much kinetic energy will it have once it is released?

Back

30J

Front

A 4kg object moves at 3m/s. How much kinetic energy does it have?

Back

The kinetic energy (KE) can be calculated using the formula KE = 0.5 * m * v^2, where m is mass and v is velocity. For this object, KE = 0.5 * 4kg * (3m/s)^2 = 18 Joules.

Front

An object with 25J of potential energy is resting at the edge of a cliff. If it falls, how much kinetic energy does it have just before it hits the ground?

Back

25J
