Forces and Force Diagrams

Front

What is the definition of Force?

Back

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

Front

What is the unit of Force?

Back

The unit of force is the Newton (N).

Front

What is Gravitational Force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.

Front

What is Normal Force?

Back

Normal force is the support force exerted upon an object that is in contact with a stable surface.

Front

What is Friction Force?

Back

Friction force is the resistance that one surface or object encounters when moving over another.

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 Push/Pull Force?

Back

Push/pull force refers to the force applied to an object to move it away from or towards the source of the force.

Front

What is the relationship between mass and force?

Back

According to Newton's second law, force is equal to mass times acceleration (F = ma).

Front

What is an example of a balanced force?

Back

An example of balanced forces is a book resting on a table, where the gravitational force is balanced by the normal force.

Front

What is an example of an unbalanced force?

Back

An example of unbalanced forces is a soccer ball being kicked, where the force of the kick is greater than the friction opposing it.
