Front

Where does a tossed baseball have the greatest kinetic energy?

Back

At the highest point of its trajectory.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

What is the formula for kinetic energy?

Back

Kinetic Energy = 1/2 mv² (where m is mass and v is velocity).

Front

What is the formula for potential energy?

Back

Potential Energy = mgh (where m is mass, g is acceleration due to gravity, and h is height).

Front

What is the difference between renewable and non-renewable energy?

Back

Renewable energy can be replenished naturally (like solar or wind), while non-renewable energy cannot (like fossil fuels).

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.
