Intro to Forces Review

Front

What is a force?

Back

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

Front

What happens when two forces are balanced?

Back

When two forces are balanced, they cancel each other out, and the object does not move.

Front

What happens when forces are unbalanced?

Back

Unbalanced forces cause an object to move in the direction of the stronger force.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass, such as the Earth pulling objects towards it.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion between magnets or magnetic materials.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is an example of a contact force?

Back

An example of a contact force is friction, which occurs when two surfaces rub against each other.

Front

What is an example of a non-contact force?

Back

An example of a non-contact force is gravitational force, which acts at a distance.
