Newton's Laws

Question 1

Newton’s second law

Answer 1

When a force is applied to an object it accelerates in the direction of the net force. The acceleration is directed proportional to the net force and inversely proportional to the mass of the object

Question 2

Newton’s third law

Answer 2

When object A exerts a force on object B; object B simultaneously exerts an oppositely directed force of equal magnitude on object A

Question 3

Newtons law of universal gravitation

Answer 3

Every object in the universe attracts every other object I. The universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of distance between their centers.

Question 4

Balanced forces

Answer 4

0 net force

Question 5

FN =Fg

Answer 5

Normal force = weight

Question 6

Inertia

Answer 6

The property of a body that resists any change in its state of rest
The greater the mass, the greater the inertia
If an object has mass, it has inertia

Question 7

Fnet or resultant force

Answer 7

A single force that has the same effect as the original forces acting together.
F1 + F2 + F3… = Fnet

Question 8

Newton’s first law

Answer 8

An object continues in a state of rest or uniform velocity unless acted upon by a force
