Work, Power, and Energy

Front

The kinetic energy of an object increases as its __________ increases.

Back

velocity

Front

Energy from a compressed spring would be an example of...

Back

elastic

Front

Energy of a rock perched on a cliff is an example of...

Back

gravitational

Front

The SI unit for energy is the _____________.

Back

joule

Front

What is the imaginary boundary called when used to describe energy transformations in objects?

Back

system

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity)

Front

What is potential energy?

Back

Energy stored in an object due to its position or configuration.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is work in physics?

Back

Work is done when a force causes an object to move; calculated as W = Fd (where F is force and d is distance).

Front

What is power in the context of work?

Back

Power is the rate at which work is done; calculated as P = W/t (where W is work and t is time).
