What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

Front

What factors affect gravitational force?

Back

The mass of the objects and the distance between them.

Front

What is normal force?

Back

Normal force is the force exerted by a surface to support the weight of an object resting on it.

Front

What is frictional force?

Back

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

Front

What is applied force?

Back

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

Front

What is tension force?

Back

Tension force is the pulling force transmitted through a string, rope, or cable when it is pulled tight.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
