Types of Forces

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, change its speed, or change its direction.

Front

What is gravitational force?

Back

Gravitational force is 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 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 normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.

Front

What happens when the applied force is greater than the frictional force?

Back

The object will start to move in the direction of the applied force.

Front

What is the relationship between mass and gravitational force?

Back

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

Front

How does friction affect motion?

Back

Friction opposes motion, making it harder for objects to slide past each other.

Front

What is the effect of gravity on objects in free fall?

Back

All objects in free fall experience the same gravitational acceleration, regardless of their mass.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents an object from starting to move, while kinetic friction acts on an object that is already in motion.
