What is a magnetic force?

Back

A magnetic force is a push or pull that occurs between magnets or magnetic materials. It can attract or repel objects.

Front

What is a gravitational force?

Back

Gravitational force is the force of attraction between two objects due to their mass. It pulls objects towards each other, like how Earth pulls us down.

Front

What is an applied force?

Back

An applied force is a force that is applied to an object by a person or another object. For example, pushing a door open.

Front

What is a normal force?

Back

A normal force is the support force exerted upon an object that is in contact with another stable object. It acts perpendicular to the surface.

Front

What is a tension force?

Back

A 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 a frictional force?

Back

Frictional force is the force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is a weight force?

Back

Weight force is the force exerted by gravity on an object. It is calculated by multiplying the mass of the object by the acceleration due to gravity.

Front

What is a spring force?

Back

Spring force is the force exerted by a compressed or stretched spring. It follows Hooke's Law, which states that the force is proportional to the displacement.

Front

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

Back

When the applied force is greater than the frictional force, the object will start to move in the direction of the applied force.

Front

What is the role of normal force in motion?

Back

Normal force supports the weight of an object resting on a surface and prevents it from falling through the surface.
