... Keep it going: It usually requires very little force to keep a trailer going—just enough to overcome the friction between the wheels and the axles. (You can coast on a bicycle for a long way.) Newton’s first law says that an object will continue to move in a straight line at constant speed unless it ...

Momentum
... Newton's second law as discussed in an earlier unit. Newton's second law (Fnet=m*a) stated that the acceleration of an object is directly proportional to the net force acting upon the object and inversely proportional to the mass of the object. When combined with the definition of acceleration (a=ch ...

The more flexible area at the center of a racket is known as the “sweet spot.” Striking a tennis ball near the edge of the racket imparts greater momentum to the ball, but the shock of the impact is transferred to the player’s arm. Hitting a b ...

6. Friction A) Overview B) Friction C) Kinetic Friction
... B) Friction In the last unit we introduced several new forces. The gravitational force is a fundamental force of nature that exists between any two objects of any size that have mass. In this unit, we will introduce a force, friction, that is more similar to the contact forces we discussed in the la ...

(There is no friction in this model.) _____________________________________________ 5. Predict: Suppose a cart with no fans has a starting velocity o ...

Investigation 1
... A student driving a car starts from rest and accelerates at a rate of 2 m/s2 for 10 seconds. When you answer the following questions, note down (for yourself) how and why you performed the steps that allowed you to arrive at your answer. This will help you remember how to solve the ...
