Newtons laws

Question 1

Newtons first law

Answer 1

If the resultant force on stationary object is zero, the object will remain stationary. If the resultant force on a moving object is zero it’ll just carry on moving at the same velocity (same speed and direction).

Question 2

Newtons second law

Answer 2

f = m x a
Resultant force = mass x acceleration

Question 3

Newtons third law

Answer 3

When two objects interact, the forces they exert on each other are equal and opposite.

Question 4

When will the velocity change

Answer 4

The velocity of an object will only change if a resultant force is acting on the object.

Question 5

Resistive force

Answer 5

The resistive forces will include friction with the air and friction with the road

Question 6

Forms of acceleration

Answer 6

stopping, starting, slowing down, speeding up, changing directions

Question 7

Newtons second law

Answer 7

the acceleration of an object is directly proportional to the resultant force acting on the object and inversely proportional to the mass of the object

Question 8

Inertial mass

Answer 8

The inertial mass is a measure of how difficult it is to change the velocity of an object

Answer 9

An object with large inertial mass will require larger force to produce a given acceleration than an object with a smaller inertial mass
