Newton's Laws Test Review Flashcardizz

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 a net external force.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m) or a = F/m.

Front

If a 25 kg crate is stopped by a 400 N force, what is the acceleration?

Back

16 m/s².

Front

What does it mean if an object is moving at a constant velocity?

Back

The net force acting on the object is zero.

Front

What is the net force on an object moving at constant velocity when a force is applied?

Back

0 N.

Front

How does mass affect acceleration when the same force is applied?

Back

If the mass is increased, the acceleration decreases.

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.

Front

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

Back

F = m * a.

Front

What is Newton's Third Law of Motion?

Back

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

Front

When a mosquito hits a bus windshield, what can be said about the forces involved?

Back

The force on the mosquito is equal to the force on the bus.
