• time

• distance

• mass

• velocity

In the kinetic energy formula, what does 'v' represent?

• vibration

• voltage

• velocity

• volume

What is the unit of measurement for kinetic energy?

• watts (W)

• joules (J)

• newtons (N)

• meters (m)

If the speed is doubled , KE will increase by __________ times

• 8
• 4

How is force related to kinetic energy?

• Force has no effect on kinetic energy

• Force is directly related to the kinetic energy of an object.

• Kinetic energy is not affected by force

• Force is inversely related to kinetic energy

Explain the relationship between force and kinetic energy using an example.

• Kinetic energy causes force to decrease

• Force and kinetic energy are interchangeable terms

• The relationship between force and kinetic energy is that force can change the kinetic energy of an object.

• Force and kinetic energy are completely unrelated

What happens to the kinetic energy of an object when the force acting on it increases?

• Increases

• Becomes negative

• Decreases

• Remains constant

What happens to the kinetic energy of an object when the force acting on it decreases?

• Decreases

• Becomes negative

• Remains constant

• Increases

How does the mass of an object affect its kinetic energy when the force acting on it remains constant?

• The kinetic energy increases as the mass of the object increases.

• The kinetic energy decreases as the mass of the object increases.

• The kinetic energy remains constant regardless of the mass of the object.

• The kinetic energy is not affected by the mass of the object.
