Front

What is the best hypothesis for the experiment with a balloon launcher?

Back

If the mass of the balloon increases, then the force needed by the launcher to move the balloon will also need to increase.

Front

What is a unit of distance?

Back

meter (m)

Front

When does an object have no kinetic energy?

Back

When it's at rest.

Front

What does the Law of Conservation of Energy state?

Back

The total amount of energy is conserved.

Front

Does increasing an object's mass increase its kinetic energy?

Back

True.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

What is the formula for gravitational potential energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the relationship between mass and force according to Newton's second law?

Back

Force equals mass times acceleration (F = ma).
