Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the definition of net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

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

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is weight?

Back

The force of gravity acting on an object, calculated as weight = mass × gravity (W=mg).

Front

What is friction?

Back

A force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is tension force?

Back

The pulling force transmitted through a string, rope, or cable when it is pulled tight.
