Newton's Laws of Motion - Honors Physics Review 2024

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 a constant velocity 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 terminal velocity?

Back

The constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

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

Back

As mass increases, acceleration decreases if the net force remains constant.

Front

What is air resistance?

Back

A force that opposes the motion of an object through the air, increasing with speed.

Front

What happens to the acceleration of an object if the net force acting on it is doubled?

Back

The acceleration of the object will also double, assuming mass remains constant.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration (F = ma).

Front

What is the effect of a parachute on a skydiver's fall?

Back

A parachute increases air resistance, reducing the skydiver's terminal velocity and allowing for a safer landing.

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.
