Identifying Types of Forces

What is friction?

• A force that opposes the motion of an object when it is in contact with another surface.

• A type of energy that is released during motion.

• A measure of how fast an object can move without stopping.

• A force that accelerates an object in the direction of motion.

What is an example of a non-contact force?

• Frictional force

• Tension force

• Gravity

• Applied force

What is tension force?

• The force exerted by a compressed spring.

• The pulling force transmitted through a string, rope, or wire when it is pulled tight.

• The force that opposes the motion of an object.

• The gravitational force acting on an object.

Force that resists motion between two surfaces.

• friction

• gravity

• inertia

• momentum

What is normal force?

• The gravitational force acting on an object.

• The support force exerted upon an object that is in contact with another stable object.

• The force that opposes motion between two surfaces in contact.

• The force exerted by a fluid on an object submerged in it.

What is a force that acts at a distance?

• can be applied without contact between objects

• requires physical contact between objects

• is only applicable in a vacuum

• is always attractive in nature
