Inv 2 Balls, Ramps & Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What is potential energy?

Back

Potential energy is the energy of position.

Front

How does speed affect kinetic energy?

Back

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

Front

How does height affect potential energy?

Back

Objects at higher heights have more potential energy.

Front

What is speed?

Back

Speed is the relationship between two variables: distance and time.

Front

What is gravity?

Back

Gravity is an invisible force that pulls objects towards the center of the Earth.

Front

What happens when objects collide?

Back

When objects collide, energy can transfer from one object to another, thereby changing their motion.

Front

What is energy transfer?

Back

Energy is transferred when work is done. Work is the action of moving a mass.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

How does the size and speed of an object affect work?

Back

The larger the moving object and the faster it is traveling, the more work it can do when it collides with another object.
