M1 Flashcards
What does the area under a speed time graph show?
Distance travelled
What does the gradient if a speed time graph show?
The acceleration of the particle.
Area of a trapezium = ?
0.5(a+b) x h
W = ?
mg
F = ?
ma
Fmax = ?
(mew)R
If tanθ is greater or equal to mew, for a particle on a rough inclined plane, what will the particle do?
It will remain at rest.
When can you treat a connected system as a particle?
When all parts are moving in the same straight line.
Momentum = ?
Mass x velocity
If a force F acts for time t, what is the impulse?
Ft
Impulse momentum principle = ?
Impulse = final momentum - initial momentum = change in momentum
I = mv - mu
Conservation of momentum principle = ?
Total momentum before impact = total momentum after impact
m1u1 + m2u2 = m1v1 + m2v2
I =
mv - mu
