REVIEW: Why Things Move?

Front

What is Tension Force?

Back

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

Front

What is Spring Force?

Back

A force exerted by a compressed or stretched spring upon any object that is attached to it.

Front

What is Air Resistance?

Back

The type of contact force that opposes the motion of an object through the air, such as your hand being pulled backwards when you stick it out of a moving car.

Front

What is Weight?

Back

The force of gravity acting on an object, calculated as the mass of the object multiplied by the acceleration due to gravity.

Front

What is Normal Force?

Back

The support force exerted upon an object that is in contact with a stable surface, equal in magnitude and opposite in direction to the weight of the object.

Front

What is the relationship between mass and weight?

Back

Weight is the gravitational force acting on an object's mass.

Front

What is Friction?

Back

A force that opposes the relative motion of two surfaces in contact.

Front

What is Applied Force?

Back

A force that is applied to an object by a person or another object.

Front

What is Elastic Force?

Back

The force exerted by a material when it is stretched or compressed, returning to its original shape.

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical contact between objects, while non-contact forces act at a distance (e.g., gravitational force).
