20
Q

What is the law of balanced forces?

A

If the vector sum of force acting upon an object is 0N, the object will not change it’s state of motion.

21
Q

What is the Law of Unbalanced Forces?

A

The the resultant force acting upon an object is not 0N, the object will experience a change in velocity, which is called acceleration

22
Q

What is the equation for resultant force?

A

Mass x Acceleration

23
Q

What is the Law of Action-Reaction?

A

If object A exerts force on Object B, B will exert a equal and opposite force on A

24
Q

What are the Rules If The Third Law(5)

A

-They come in pairs
-Are of the same nature
-have the same size
Act on the same line but have opposite directions
Act on different objects

25
Q

What is the equation for weight

A

W=mg(10m/s^2)

26
Q

What is the equation for Acceleration

A

(V-U)/T

27
Q

How to calculate the acceleration of gravity

A

Force/Mass=acceleration. acceleration x mass = force

28
Q
