Newtons laws of motion

Question 1

Newtons first law of motion

Answer 1

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Question 2

Newtons second law of motion

Answer 2

The ACCELERATION of a body is directly proportional to, and in the same direction as, the net FORCE acting on the body, and inversely proportional to its MASS.
F = ma, where F is the net force acting on the object, m is the mass of the object and a is the acceleration of the object

Question 3

Newtons third law of motion

Answer 3

When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body.
this is how we walk. Our foot pushes on the ground. the ground exerts an opposite force and pushes us forward.

Question 4

the Second Law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematical equation

Answer 4

Force = Mass X Acceleration ( Newtons )

Question 5

Newtons second law of motion involves what 3 things

Answer 5

Acceleration, force mass

Question 6

formula for acceleration

Answer 6

a = change in Velocity / time taken m/sec2
