intro to forces

Front

What is a force?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

What are contact forces?

Back

Contact forces are forces that occur when two objects are in physical contact with each other.

Front

What is weight?

Back

Weight is the measure of how much gravity is pulling on an object.

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 are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in motion.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

Front

What is an example of a non-contact force?

Back

An example of a non-contact force is magnetic force.

Front

How does friction affect motion?

Back

Friction slows down or stops the motion of an object.
