TEK 8.6 Newton's Laws of Motion Review

Front

What does Newton's third law of motion state?

Back

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

Front

What is an example of equal and opposite reaction forces?

Back

The forces exerted by a rocket's exhaust pushing downward and the rocket being pushed upward.

Front

Why is the nozzle of a rocket pointed downward?

Back

To ensure that the exhaust gases push downward, which in turn pushes the rocket upward.

Front

What happens to the weight of an object when it is on the Moon compared to Earth?

Back

The weight is less on the Moon due to lower gravitational pull.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).

Front

What is the relationship between mass and acceleration when an unbalanced force is applied?

Back

The greater the mass, the less acceleration for a given force; the smaller the mass, the greater the acceleration.

Front

What is a force?

Back

A push or pull on an object.

Front

How does an unbalanced force affect an object in motion?

Back

It causes the object to accelerate in the direction of the unbalanced force.

Front

What is the effect of friction on moving objects?

Back

Friction opposes the motion of objects, causing them to slow down.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
