Kinetic & Potential Energy Practice

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What kind of energy is in an acorn hanging from an oak tree?

Back

Potential energy is the stored energy in an object due to its position.

Front

A exercise ball is on a table 2.5 m above the ground. What is the mass of the ball if it has a GPE of 56.8 J?

Back

The mass of the ball is 2.32 kg.

Front

What kind of energy is in a rock at the edge of a cliff?

Back

Potential energy is present in a rock at the edge of a cliff due to its height.

Front

__________ is stored energy.

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is the formula for calculating gravitational potential energy (GPE)?

Back

GPE = mass (kg) × gravitational acceleration (9.81 m/s²) × height (m).

Front

If an object is moving, what type of energy does it have?

Back

Kinetic energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed of the object.

Front

What type of energy does a compressed spring have?

Back

Potential energy, specifically elastic potential energy.
