What does S in Suvat stand for?
Space/Displacement
What does the U in SUVAT stand for
Initial speed
What does V in Suvat stand for?
Final speed/velocity
What does A in Suvat stand for
Acceleration
What does T in Suvat stand for?
Time
What are the 2 types of Motion
Constant/Uniform speed/velocity (graph will be straight) and Constant/Uniform acceleration
What is the equation for displacement if you have U,V,T
U+V/2xT
What is the equation for Displacement if you have U,A,T
UT+1/2AT^2
What is the equation for displacement if you have VAT?
VT-1/2AT^2
What is the equation for displacement if you have VUA?
V^2-U^2/2A
What is the law of balanced forces?
If the vector sum of force acting upon an object is 0N, the object will not change it’s state of motion.
What is the Law of Unbalanced Forces?
The the resultant force acting upon an object is not 0N, the object will experience a change in velocity, which is called acceleration
What is the equation for resultant force?
Mass x Acceleration
What is the Law of Action-Reaction?
If object A exerts force on Object B, B will exert a equal and opposite force on A
What are the Rules If The Third Law(5)
-They come in pairs
-Are of the same nature
-have the same size
Act on the same line but have opposite directions
Act on different objects
