Kinetic Energy Flashcards

Front

Kinetic Energy

Back

The energy an object has because it is moving. The faster an object moves, the more kinetic energy it has.

Front

Potential Energy

Back

The energy an object has because of its position or state. The higher an object is, the more potential energy it has.

Front

Work

Back

The effort or force used to move an object over a distance. It's how much energy is transferred.

Front

Power

Back

The rate at which work is done. It's how quickly energy is transferred.

Front

Force

Back

A push or pull that can change an object's motion or shape.

Front

Mechanical Advantage

Back

The ratio of the output force to the input force in a simple machine. It tells you how much easier a machine makes a task.

Front

Friction

Back

A force that opposes motion between two surfaces in contact. It slows things down.

Front

Energy Conservation

Back

The idea that energy cannot be created or destroyed, only changed from one form to another.

Front

Momentum

Back

A measure of how much motion an object has. It depends on the object's mass and velocity.

Front

Acceleration

Back

The rate at which an object's velocity changes. It can be speeding up, slowing down, or changing direction.
