... 2. What is the average force needed to stop a bullet of mass 20.0 grams and speed 500 m/s as it penetrates a wooden block to a distance of 12.0 cm? (2.08×104 N) Assuming a constant force, how long does it take to stop the bullet? (0.48 ms) 3. Suppose a child on a sled has just reached the bottom of ...

Newton`s Laws Notetakers
... INERTIA = a measure of a body’s ability to resist changes in velocity. (the greater the mass of a body, the less it will accelerate under the action of an applied force) Why is it easier to push a Volkswagen then a Mack truck? Newton’s Second and Third Laws Newton’s Second Law: ______________ The ac ...

... Work and Energy Newton’s Second Law describes the vector relationship between force, acceleration and time. Work and Energy is a restatement of Newton’s Second Law, and describes the scalar relationship between force, position and speed. The work done by a force Let the change in the position of a ...

Gravity-centripetal acceleration
... Force and Circular Motion: • In order for an object to undergo circular motion, a force must act. Picture an object that has some velocity. What will happen to it if no forces act on it? Well, according to the first law, it will continue to move with a constant velocity. It will follow a straight-l ...
