TEST PAPER VERIFIED QUESTIONS AND
SOLUTIONS GRADED A+

●● Inertia
Answer: If an object is at rest, it stays at rest unless acted on by an
outside force. An object in motion, stays in motion at constant velocity,
unless acted on by an outside force


●● 2nd Law of Motion
Answer: A=F/m


●● A=F/m
Answer: The acceleration of an object produced by a net force is directly
proportional to the magnitude of the net force, in the same direction as
the net force, and indirectly proportional to the mass of the object.


●● 3rd Law of Motion
Answer: Action/Reaction


●● Action/Reaction
Answer: When one object exerts a force on another object, the second
object exerts and equal and opposite force on the first object.

, ●● Law of Universal Gravitation
Answer: Every object attracts every other object with a force.


●● In physics, work is defined as
Answer: the product of the net force on the object and the distance
through which the object is moved; force X distance
