Type of Energy - JSS2 Basic science Past Questions and Answers - page 1
What is kinetic energy?
Energy of motion
Energy of rest
Energy of heat
Energy of light
Which factor does NOT affect an object's kinetic energy?
Mass
Velocity
Temperature
Both a) and b)
What is the formula for kinetic energy?
KE = mass * velocity
KE = mass + velocity
KE = 0.5 * mass * velocity^2
KE = 0.5 * mass + velocity^2
What does the kinetic energy assumption state?
All moving objects have energy because of their motion.
All stationary objects have energy because of their motion.
Only heavy objects have energy.
Only light objects have energy.

Remains the same
Doubles
Which of the following statements about kinetic energy is true?
Kinetic energy depends only on an object's mass.
Kinetic energy depends only on an object's velocity.
Kinetic energy depends on both an object's mass and velocity.
Kinetic energy is independent of mass and velocity.
Which energy is NOT a form of kinetic energy?
Mechanical energy
Electrical energy
Thermal energy
Sound energy
If an object's mass increases but its velocity remains the same, what happens to its kinetic energy?
Increases
Decreases
Remains the same
Doubles
