Define acceleration
Rate of change of velocity with respect to time
Define displacement
Distance in a given direction
Differentiate between vector and scalar quantities
Vector: direction and magnitude
Scalar: magnitude only
Newtons first law
A body at rest will remain at rest and a body in motion will remain in motion unless acted upon by an external force
Define pressure
Force per unit area
Give a formula for pressure
P = F/A
Newtons second law
When a body is acted upon by an unbalancing force, the rate of change of momentum is proportional to the force and takes place in the direction of the force
Newtons first law is also known as
Law of inertia
Newtons second law is also known as
Law of acceleration
Newtons third law
For every action there is an equal and opposite reaction. Action and reaction do not occur on the same plane
F = MA is given by which of Newtons laws
2nd - law of acceleration
Archimedes principle states that
When an object is fully or partially immersed in a fluid it experiences an upthrust equal in magnitude to the weight of the fluid displaced
