Momentum and Impulse notes
... What does momentum and impulse have to do with each other? Momentum = mv If velocity changes, momentum changes, and acceleration (either + or –) occurs But we know: 1. for acceleration to occur, a force has to be applied. 2. If a given force is applied over a longer time, more acceleration occurs. ...

... Later, the proportionality was made into an equation a = F/m, or F = ma and force was defined as more than a push or pull. The units for force are taken from ma, kgm/s2, which are called Newtons, in honor of Isaac Newton. For example, a net force of 1 N acting on a 1 kg object causes it to accele ...

Activity P08: Newton`s Second Law
... The acceleration of an object is directly proportional to and in the same direction as the net force, and inversely proportional to the mass of the object: F a net m a is acceleration, Fnet is net force, and m is mass. Applying Newton’s Second Law to the static setup used in this activity for an o ...

Special Rotational Dynamics Outline
... When the net torque on an object is zero, its angular momentum is conserved (constant). This is why, for example, an ice skater spins faster when he/she pulls in arms to decrease moment of inertia, I. The angular momentum, Iω is constant, so if I goes down, angular velocity (ω) must go up. Likewise, ...
