Newton's Laws & Forces Review

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 with the same speed and in the same direction unless acted upon by an unbalanced 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 friction?

Back

A force that opposes the motion of an object.

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate because the net force acting on it is not zero.

Front

What is a balanced force?

Back

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

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, affecting the motion of objects on Earth.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is air resistance?

Back

A type of friction that acts against the motion of an object moving through air.
