Forces and Newton's Laws

Front

Mass is defined as _____

Back

the amount of matter in an object

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What is inertia?

Back

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

Front

Balanced or unbalanced forces: What does it mean?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of objects that move through the air.

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 formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

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.
