Constant Acceleration Equations & Newton's Laws Flashcards
What are the constant acceleration equations?
- v=u+at
- s=ut+0.5at^2
- s=(u+v both over 2)t
- v^2=u^2+2as
- s=vt-0.5at^2
What do the letters in suvat mean?
- s = displacement
- u = initial velocity
- v = final velocity
- a = acceleration
- t = time
What is acceleration due to gravity?
An object moving through the air experiences acceleration due to gravity. This is written as g and you can always assume that g=9.8m/s^2 unless you’re given a different value. It always works vertically downwards.
What is Newton’s first law?
A body will stay at rest or maintain a constant velocity unless a resultant force acts on the body.
What is Newton’s second law?
The overall resultant force acting on a body is equal to the mass of the body multiplied by the body’s acceleration. (F=ma)
What is Newton’s third law?
For two bodies A and B, in contact with each other, the force exerted by A on B is equal in magnitude but opposite in direction to the force exerted by B on A.
