Forces & Newton's Laws Test

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

Define net force.

Back

The overall force acting on an object when all the individual forces are combined.

Front

What happens when the net force on an object is zero?

Back

The object will remain at rest or continue to move at a constant velocity.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass. Weight (W) = Mass (m) x Gravitational acceleration (g).

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate, resulting in a change in its motion.

Front

Explain inertia.

Back

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

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 effect of gravity on weight in space?

Back

Weight decreases in space because gravitational pull is weaker, but mass remains constant.

Front

What is Newton's Third Law of Motion?

Back

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