M1 Flashcards
What is a Impulse
Change in momentum
Final Momentum - Initial Momentum
mv=mu
What is the conservation of momentum principle
Momentum before = Momentum after
m1u1+m2u2=m1v1+m2v2
What is time measured in
Seconds (S)
What is displacement measured in
Metres(m)
What is velocity measured in
Metres per second(m/s)
What is acceleration measured in
Metres per second per second (m/s²)
What is the value of gravity in M1
9.8m/s²
What is the gradient of a speed time graph equal to
Acceleration
What is the area under a speed time graph
Distance
What is newtons first law
F=ma
Force= Mass x acceleration
Define Weight
Mass x gravity
What are the SUVAT Formulae
v=u+at s=((u+v)/2)t v²=u²+2as s=ut+1/2at² s=vt-1/2at²
What are the other names for negative acceleration
Deceleration
Retardation
What does SUVAT stand for
S-Displacement U-Initial Velocity V-Final Velocity A-Acceleration T-Time
What is a moment Equal to
Force x distanc
