What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact with each other.

Front

What is gravitational force?

Back

Gravitational force is the force that attracts two bodies towards each other, commonly experienced as the weight of an object due to Earth's gravity.

Front

What is support force?

Back

Support force, also known as normal force, is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is air resistance?

Back

Air resistance is a type of frictional force that opposes the motion of an object through the air, often causing it to slow down.

Front

What is applied force?

Back

Applied force is a force that is applied to an object by a person or another object, causing it to move or change its motion.

Front

What is tension force?

Back

Tension force is the force that is transmitted through a string, rope, or wire when it is pulled tight by forces acting from opposite ends.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (Weight = mass x gravity).

Front

What happens to an object in free fall?

Back

An object in free fall experiences only the force of gravity acting on it, causing it to accelerate downwards at 9.8 m/s² near Earth's surface.

Front

How does friction affect motion?

Back

Friction can slow down or stop the motion of an object, depending on the surfaces in contact and the amount of force applied.

Front

What is the role of gravity in falling objects?

Back

Gravity pulls objects towards the Earth, causing them to accelerate downwards when they are in free fall.
