Momentum Review - KEY
... 1. Distinguish between mass and momentum. Which is inertia and which is inertia in motion. (7.1) An objects inertia is basically defined by its mass. An objects momentum is its mass multiplied by its velocity. This means that Mass is Inertia and Momentum is inertia in motion. 2. a. Which has the gre ...

... Fnet = ma (or F = ma ) Newton’s second law EXAMPLE: An object has a mass of 25 kg. A tension of R 50 n and a friction force of 30 n are acting on it as shown. What is its acceleration? 50 n SOLUTION: Ff The vertical forces W and R 30 n cancel out. W The net force is thus Fnet = 50 – 30 = 20 n (+x ...

Gr. 11 Physics Forces
... We will use a spring scale to measure the size of forces. First you need to calibrate the spring scale. Hold the scale horizontally or vertically just as you will use it when measuring, but without pulling on the hook. Adjust the scale (a sliding cover or nut at the top) so it reads zero. The scale ...

Momentum - Net Start Class
... Impulse explains the operation of air bags, etc. An air bag increases the time that the change in momentum occurs over. The product of the force and t must equal the change in momentum. If t is increased, then the force must be decreased in order for their product to be constant. Angular momentum ...

Momentum and Its Conservation
... Systems can contain any number of objects, and the objects can stick together or come apart in a collision. Under these conditions, the law of conservation of momentum states that the momentum of any closed, isolated system does not change. This law will enable you to make a connection between condi ...
