Newton's Laws - 8th grade SOL Review Station Activity

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 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 formula to calculate acceleration?

Back

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

Front

If a car's mass is 1,000 kg and a force of 3,000 N is applied, what is the acceleration?

Back

3 m/s² (a = F/m = 3000 N / 1000 kg)

Front

What happens to the acceleration of an object if the mass is doubled while the force remains constant?

Back

The acceleration is halved.

Front

What is the definition of frictional force?

Back

Frictional force is the force that opposes the motion of an object.

Front

If a box is pushed with a force of 10 N and moves at constant velocity, what can be said about the frictional force?

Back

The frictional force is equal to 10 N in the opposite direction.

Front

What is the net force acting on an object in equilibrium?

Back

The net force is zero.

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle.
