forces defintions

Question 1

Define Newtons first law

Answer 1

If the net force acting on an object is zero, the object will maintain its state of rest of uniform motion

Question 2

Define Newtons second law

Answer 2

If the net force acting on an object is not zero, the object will accelerate in the direction of the net force. The acceleration is directly proportional to the force, and inversely proportional to its mass.

Question 3

Define Newtons third law

Answer 3

If one object exerts a force onto a second, the second, in that exact instant will exert a force equal in magnitude and opposite in direction on the first

Question 4

Define mass

Answer 4

The amount of substance in an object

Question 5

Define Weight

Answer 5

The force of gravity acting on an object in a gravitational field

Question 6

Define applied force

Answer 6

Any force applied onto an object by another that either pushes or pulls it

Question 7

Define tension

Answer 7

A pulling force exerted on an object by a rope or a string

Question 8

Define normal

Answer 8

Force exerted on an object by a surface in contact with it

Question 9

Define Friction

Answer 9

Force that opposes the slide of 2 surfaces across each other

Question 10

Define force of gravity

Answer 10

Force of attraction between any 2 object due to their mass
