Paper One: Further Mechanics Flashcards
1
Q
Define Impulse.
A
Impulse is a change in momentum.
2
Q
What is the equation for Impulse?
A
Impulse = Force x Time ( I = F x (delta) t ).
3
Q
What is an elastic collision?
A
A collision where both momentum AND kinetic energy are conserved.
4
Q
What is the equation for kinetic energy that relates K.E. and Momentum?
A
K.E. = P^2 / 2M.
5
Q
What is the equation for velocity that relates angular velocity and the radius of the circle?
A
V = W (omega) x R.
6
Q
What is the equation for acceleration that relates angular velocity and the radius of the circle?
A
a = W (omega)^2 x R.
7
Q
What is centripetal force?
A
A resultant force required to maintain circular motion.
8
Q
What two equations related Newton’s second law and the force equation for circular motion?
A
F = M x A = M V^2 / R.
