Forces

Front

What is a force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

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 weight force?

Back

Weight force is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (9.8 m/s²).

Front

What is thrust?

Back

Thrust is the force that propels an object forward, often produced by engines or propellers.

Front

What is buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on an object submerged in it, which counteracts the weight of the object.

Front

What is normal force?

Back

Normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

What is applied force?

Back

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

Front

What is tension force?

Back

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

Front

What is net force?

Back

Net force is the total force acting on an object, calculated by combining all individual forces acting on it, taking direction into account.

Front

What is the principle of action and reaction?

Back

For every action, there is an equal and opposite reaction; this means that forces always occur in pairs.
