What is kinetic energy?

• The energy of heat

• The energy of motion

• The energy of light

• The energy of rest

What is described by an object's direction and speed?

• Pulling force

• Kinetic energy

• Friction force

• Potential energy

What is the net force?

• The force of rest

• The combination of all forces acting on an object

• The force of motion

• The force of gravity

What can cause changes in an object's speed or direction of motion?

• Pulling force

• Forces that do not sum to zero net force

• Friction force

• Forces that sum to zero net force

What happens when objects collide?

• The energy from both objects is halved

• The energy from both objects is doubled

• The energy from one object transfers to another object

• The energy from one object is lost

What does speed describe?

• How slow an object is moving

• The force acting on an object

• How fast an object is moving

• The direction of an object's motion

What tends to stay in motion unless acted on by a force?

• Objects at rest

• Objects with low mass

• Objects with high mass

• Objects in motion

What is a force?

• The energy of motion

• The combination of all forces acting on an object

• The energy of rest

• Any push or pull that causes an object to move, stop, or change speed or direction
