Work, Power, and Energy Review

Front

What kind of energy is present when a person climbs a ladder?

Back

Both potential and kinetic energy are present.

Front

At which point is potential energy greatest when climbing a ladder?

Back

At the highest point (W).

Front

If Aria triples her speed on her bicycle, by how many times does her kinetic energy increase?

Back

Her kinetic energy increases by 9 times.

Front

What types of energy does a television transform electrical energy into?

Back

Light, thermal, and sound energy.

Front

What type of energy transfer occurs when Gustavo drops a ball from a height?

Back

Gravitational Potential energy transforms to Kinetic energy, then to Sound energy.

Front

Define Work in physics.

Back

Work is the energy transferred when a force is applied over a distance.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

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

Front

How does height affect Potential Energy?

Back

Potential Energy increases with height; PE = mgh, where h is height.

Front

What is the relationship between Work and Energy?

Back

Work done on an object results in a change in its energy.
