Newton's First and Second Law

Front

What is Newton's 1st Law?

Back

An object at rest will stay at rest, and an object in motion will stay in motion, unless an unbalanced force acts upon it.

Front

What is Newton's 2nd Law?

Back

Acceleration depends on two variables: the mass of the object and the amount of force applied.

Front

What is inertia?

Back

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

Front

What is net force?

Back

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

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in a net force of zero.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate, resulting in a net force greater than zero.

Front

How does mass affect acceleration?

Back

According to Newton's 2nd Law, greater mass results in less acceleration for the same amount of force.

Front

What is the formula for Newton's 2nd Law?

Back

The formula is F = ma, where F is force, m is mass, and a is acceleration.

Front

What happens to a resting object when no force acts on it?

Back

It will remain at rest due to inertia.

Front

What happens to a moving object when no force acts on it?

Back

It will continue to move at a constant speed in a straight line due to inertia.
