Question 1

A force involves

Answer 1

The interaction of two objects and can produce a change in the state of motion of an object by pushing or pulling it
F= mass x accel

Question 2

Newtons:

Answer 2

1N= amount of force it takes to accelerate a 1kg body at 1m/s squared
-represented as a ratio of force to body weight= %BW

Question 3

Point of application

Answer 3

The specific point at which the force is applied to an object

Question 4

Line of Action

Answer 4

A straight line in the direction in which the force is acting

Question 5

Newtons First Law

Answer 5

Law of inertia
-a body will remain at rest or continue to move with a constant velocity unless acted on by an outside force
Increase mass= increase inertia

Question 6

Inertia is used

Answer 6

To describe an objects resistance to motion and is directly related to the mass of the object
Increase mass= increase inertia

Question 7

Newtons Second Law

Answer 7

Law of acceleration
-net force= mass x acceleration

Question 8

Newtons 3rd Law

Answer 8

Action/ reaction
-for every action there is an equal and opposite reaction
-forces always act in pairs
-these paired forces are equal and opposite

Question 9

Momentum

Answer 9

Designated to P
-the quantity of motion of an object
P= m x velocity
