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 unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

Acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force needed to accelerate the object.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What are the SI units for force?

Back

Newtons (N).

Front

If a force of 26 N is applied to two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball has greater acceleration?

Back

The ball with a mass of 0.52 kg has greater acceleration.

Front

What does the equation F=ma represent?

Back

It represents the relationship between force (F), mass (m), and acceleration (a).

Front

What happens to an object when a net force is applied?

Back

It will accelerate in the direction of the net force.

Front

How does a rocket take off according to Newton's Third Law?

Back

The hot gases move in one direction, while the rocket moves in the opposite direction with equal force.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases.
