... true"!). In relativity we must change Newton's II law F = ma since m is not constant. We can use the momentum instead : F = ma = m(v-u) = mv - mu and then impulse = Ft = change in momentum = p = mv - mu which for an infinitely short time dt becomes: Fdt = dp and dividing with dt then: F = dp/dt (f ...

Angular Momentum (AIS)
... If both of these wheels accelerate from rest to the same angular velocity ω in the same time t. • The angular acceleration, α, must be the same for both wheels. Also, the total angle turned through must be the same. • But, when moving with angular velocity ω, the particles of wheel B are moving fast ...

... This law is sometimes called the Law of Inertia. This means if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed. ...
