Noah Newton`s 2nd Law on Hills Class Exercises
... 2. Jimmy is going to pull his 1000 kg motorboat out of the water and up the 18° slope of the boat ramp. i. Jimmy’s truck and boat trailer are parked on the boat ramp, 10 m uphill from the water. He gets in the truck, eases off the brake, and allows the trailer to accelerate all the way down the ram ...

03. Momentum
... • A “System” is an object or a collection of objects. • The Total Momentum of a system equals the vector sum of the momenta of all the objects in the system: • PTotal System = P1 + P2 (for a system of two objects) • Also called the “Net Momentum”: PNET or PTOT • EXAMPLES: – We have two cars, each wi ...

AP Physics – Friction
... The value of the coefficients depends on the two surfaces in contact with one another. These values are found by experiment. Useful tables can sometimes be found that have the different coefficient values for common materials worked out and ready for use by the enterprising physicist. ...

Going Down
... with little change in velocity. You could imagine that if all friction were eliminated, the ball might roll at the same velocity forever. Galileo did many experiments on the motion of balls on very smooth surfaces. He concluded that in the ideal case, horizontal motion was eternal: it would never st ...

6 Newton`s Second Law of Motion–Force and Acceleration
... Both liquids and gases are called fluids because they flow. • Fluid friction occurs as an object pushes aside the fluid it is moving through. • The friction of liquids is appreciable, even at low speeds. • Air resistance is the friction acting on something moving through air. ...
