Newton's Law

Question 1

Newton’s First Law

Answer 1

An object remains in the same state of motion unless a resultant force acts on it.

Question 2

Newton’s Second Law

Answer 2

F=ma

Force = mass x acceleration

The equation shows that the acceleration of an object increases if the resultant forces increases, and decreases if the mass of the object increases.

Question 3

Newton’s Third Law

Answer 3

Whenever two object interact, they exert equal and opposite forces onto each other.

“every action has an equal and opposite reaction.”

Question 4

Weight, Mass, Gravitational Field Strength

Answer 4

Weight = mass x gravitational field strength
