Front

What is mass?

Back

Mass is how much matter is in an object.

Front

What is weight?

Back

Weight is the gravitational pull on an object.

Front

What describes the particles in a solid?

Back

They vibrate in place within a fixed volume.

Front

What happens to potential energy when two objects with different masses fall from the same height?

Back

The object with the larger mass has more potential energy.

Front

What determines the amount of kinetic energy in an object?

Back

Kinetic energy is determined by mass and speed.

Front

How do the molecules in ice water compare to those in hot tea?

Back

The molecules in the ice water move slower than in the hot tea.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy = 1/2 * mass * speed^2.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass.

Front

What happens to the kinetic energy of an object if its speed doubles?

Back

The kinetic energy increases by a factor of four.

Front

What is potential energy?

Back

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