Understanding Kinetic Energy

What is kinetic energy?

• Energy due to an object's height

• Energy stored in an object at rest

• Energy of an object due to its movement

• Energy from chemical reactions

Which factor does NOT affect the kinetic energy of an object?

• Color of the object

• Mass of the object

• Speed of the object

• Direction of the object

If a car and a truck are moving at the same speed, which has more kinetic energy?

• The truck, because it has greater mass

• The one with more fuel

• They have the same kinetic energy

• The car, because it is smaller

What happens to the kinetic energy if the speed of an object is doubled?

• It increases by four times

• It triples

• It remains the same

• It doubles
