Newton's Laws Test Review

Front

What is Newton's 1st 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

How does Newton's 1st Law apply to satellites orbiting Earth?

Back

Satellites continue to move in a straight line at constant speed due to inertia, while the gravitational force from Earth acts as the external force that changes their direction.

Front

What are action and reaction forces according to Newton's 3rd Law?

Back

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

Front

In the context of a game controller at rest, what are the action and reaction forces?

Back

Action force = gravity acting downwards; Reaction force = normal force exerted by the table acting upwards.

Front

What happens during a collision between a semi truck and a small car traveling at the same speed?

Back

The impact force is equal for both vehicles, regardless of their mass.

Front

What is the significance of the normal force in physics?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

How does stepping off a boat onto a dock illustrate Newton's 3rd Law?

Back

As a person steps forward onto the dock, the boat moves backward due to the equal and opposite reaction to the person's action.

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 according to Newton's 2nd Law?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object, calculated as weight (W) = mass (m) × gravitational acceleration (g).
