definition of scalar
magnitude but no direction
1 of 11
scalar quantities
speed,distance,mass,temperature,time.
2 of 11
definition of vector
has magnitude and direction
3 of 11
vector quantities
force ,velocity, displacement, acceleration, momentum
4 of 11
what is a force
push or pull on an object caused by it interacted with something
5 of 11
definition of a contact force
when 2 object have to be touching for a force to act e.g tension in ropes,friction,air resistance
6 of 11
definition of a non contact
when object dont have to touch for the force to act e.g.. magnetic force ,gravitation force
7 of 11
newtons 1st
the force is needed to make something start moving speed up or slowdown
8 of 11
newtons 2nd
f=ma == force =mass x acceleration
9 of 11
newtons 3rd law
when 2 object interact the forces they exert on each other are equal and opposite

a van of mass of 2080 kg has an engine that provides a driving force of 5200N.at 70 mph the drag force acting on the van is 5148N. find its acceleration at 70mph.
5200-5148=52N a=f+m 52/2080=0.025 m/s^2
