Motion and Forces Unit Test Review

Front

What does Newton's Second Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

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

Back

Greater mass results in lesser acceleration when the same force is applied.

Front

What happens to the velocity of an object if the net force acting on it is zero?

Back

The velocity remains constant.

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.

Front

What is the role of friction in motion?

Back

Friction can either slow down or stop motion.

Front

How does Newton's Third Law apply to a rocket launch?

Back

The rocket pushes down on the air, and the air pushes the rocket up.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses.
