31 Pulleys
... A pulley is a simple machine having a rope that passes over a grooved wheel. A fixed pulley (see Figure 1) is attached to a solid support and changes the direction of force. The resistance force is the weight of the object being lifted. This force is applied to one end of the rope that goes over a f ...

... b. Maximum and minimum kinetic energy. ANS: The maximum kinetic energy occurs at the point where the ball is moving fastest, namely right after it leaves Larissa’s hand and right before she catches it. The minimum kinetic energy will occur when the ball is moving slowest – right at the top of the p ...

Ch. 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. ...

... In a car the driver’s head is moving horizontally at 8.0 ms-1 and collides with an air bag as shown. The time taken for the driver’s head to come to a complete stop is 1.6 x 10-1 s. This collision may be modelled as a simple horizontal collision between the head of mass 7.0 kg and the air bag. ...
