Momentum
... • When a dish falls, will the impulse be less if it lands on a carpet than if it lands on a hard ceramic tile floor ? • The impulse would be the same for either surface because there is the same momentum change for each. It is the force that is less for the impulse on the carpet because of the great ...

CHAPTER 7: Linear Momentum
... For momentum to be conserved, the system under analysis must be “closed” – not have any forces on it from outside the system. A coasting car has air friction and road friction on it, for example, which are “outside” forces and thus reduce the momentum of the car. If the ground and the air were consi ...

... In the body the skeleton forms a system of levers that allows us to move. The bones act as the levers, the joints are the fulcrums and the effort is provided by the muscle. A lever has two main functions: 1. To increase the speed at which a body can move. 2. To increase the amount of resistance that ...

Before either piece of steel has been treated to reduce friction, the force necessary to get them to perform properly is 5.8 N. After the pieces have been treated with oil, what will be the required force? Ff, before ...

Chapter 6 Newton`s Laws with Friction, and Circular Motion
... friction. This means that less force is needed to keep the object in motion, than it is to start it into motion. We should note here, that these laws of friction are empirical laws, and are not exactly like the other laws of physics. For example, with Newton’s second law, when we apply an unbalanced ...
