Kinetic and Potential Energy

Front

Energy due to motion is ____________ energy.

Back

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

Front

What kind of energy is in a person climbing a ladder?

Back

Both potential and kinetic energy are present when a person climbs a ladder. Potential energy increases as they gain height, while kinetic energy is present due to their movement.

Front

What kind of energy is in a waving hand?

Back

Kinetic energy is present in a waving hand because it is in motion.

Front

A 2600 kilogram car is moving at a speed of 25 m/s. How much kinetic energy does the car have?

Back

The kinetic energy of the car is 812,500 J.

Front

A 0.40 kilogram bird is flying at a constant speed of 8.0 m/s. What is the bird's kinetic energy?

Back

The bird's kinetic energy is 12.8 J.

Front

Define potential energy.

Back

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

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

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

Give an example of potential energy.

Back

An example of potential energy is a rock held at the top of a hill.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
