Newton's Laws of Motion - JSS2 Basic technology Past Questions and Answers - page 1
Which of the following best describes Newton's First Law of Motion?
An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity, unless acted upon by a net external force.
The acceleration of an object is directly proportional to the net force acting on it.
For every action, there is an equal and opposite reaction.
The force of gravity acts between all objects in the universe
What is the formula associated with Newton's Second Law of Motion?
F = ma
E = mc²
P = mv
W = mg
According to Newton's Third Law of Motion, when you push against a wall, the wall pushes back with a force that is:
Less than the force you applied
Equal to the force you applied
Greater than the force you applied
Dependent on the mass of the wall

What happens to the acceleration of an object if the force applied to it is doubled?
It remains the same
It is halved
It is doubled
It is quadrupled
Which of the following is an example of Newton's Third Law of Motion?
