TEK 8.6 Newton's Laws of Motion Review

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 an unbalanced 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, expressed as F=ma.

Front

What is Newton's Third Law of Motion?

Back

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

Front

How does a rocket propel itself according to Newton's laws?

Back

A rocket pushes gases backward, and in response, the rocket is pushed forward due to Newton's Third Law.

Front

What happens to a skateboard when a person jumps off?

Back

The skateboard rolls backward due to the equal and opposite force acting on it as the person jumps forward.

Front

What are action and reaction forces?

Back

Action and reaction forces are pairs of forces that are equal in size, but opposite in direction, acting on two different objects.

Front

What is inertia?

Back

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

Front

What is the significance of the net force acting on an object?

Back

The net force determines the acceleration of an object according to Newton's Second Law.

Front

What is an example of Newton's First Law in everyday life?

Back

A ball rolling on a flat surface will eventually stop due to friction, demonstrating that an unbalanced force is needed to change its motion.

Front

How do forces affect the motion of blocks in a system?

Back

Blocks will move if the net force acting on them is greater than the frictional forces opposing their motion.
