Newton's Laws

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 at the same speed and in the same direction unless acted upon by an unbalanced force.

What does inertia mean in the context of Newton's First Law?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

How does Newton's First Law apply to a sliding ice skater?

Back

A sliding ice skater will continue to slide until a force, like friction or another skater, acts on them to stop or change their direction.

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 does the term 'net force' mean?

Back

Net force is the total force acting on an object after all the individual forces are combined.

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases if the same force is applied.

What is the role of friction in motion?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

How does friction affect an object's motion?

Back

Friction can slow down or stop an object in motion.
