Types of Forces

Front

What is gravitational force?

Back

The force of attraction between two objects due to their mass. On Earth, it pulls objects towards the center of the planet.

Front

What is normal force?

Back

The support force exerted by a surface against the weight of an object resting on it, acting perpendicular to the surface.

Front

What is applied force?

Back

A force that is applied to an object by a person or another object, often resulting in movement.

Front

What is frictional force?

Back

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

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with the mass of the objects involved; more massive objects exert a stronger gravitational pull.

Front

What is tension force?

Back

The pulling force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion between two surfaces in contact, while kinetic friction acts on moving surfaces.

Front

How does surface area affect friction?

Back

Surface area does not significantly affect friction; it is primarily dependent on the nature of the surfaces in contact.

Front

What is net force?

Back

The overall force acting on an object when all individual forces are combined; it determines the object's motion.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g), where g is approximately 9.8 m/s² on Earth.
