8th Grade Potential and Kinetic Energy

Front

The energy stored in an object is _____________ energy:

Back

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

Front

If you have two objects with different masses about to fall from the same height, which one will have the greatest potential energy?

Back

The heaviest object will have the greatest potential energy because potential energy depends on mass.

Front

What type of energy is present? A diver just before she dives off the 30m platform.

Back

Potential energy is present because the diver is at a height.

Front

What type of energy is present? A swimmer in the middle of a 50m race.

Back

Kinetic energy is present because the swimmer is in motion.

Front

What type of energy is present? A baseball just before being released by the pitcher.

Back

Potential energy is present because the baseball is held at a height.

Front

Define kinetic energy.

Back

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

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (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

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.

Front

How does mass affect potential energy?

Back

Potential energy increases with mass; the greater the mass, the greater the potential energy.
