The internal resistance to the flow of fluids is termed viscosity. The net force is zero. Memorize flashcards and build a practice test to quiz yourself before your exam.

Write down the Newtons 2nd law net force mass acceleration for each mass. In this lesson we will take a look at some of the. C The ball will gain an equal amount of momentum during each meter through which it falls.

A siphon pumps water from a large reservoir to a lower tank that is initially empty. Moving object stop c. In simple terms the viscosity is nothing but thickness of a fluid.

Moving object have weight. A The ball will gain an equal amount of kinetic energy during each second. D 5 cm.

Ignore all frictional effects and assuming the pulley to be massless a b c d Show all the forces acting on both the masses in the accompanying diagram. A 2 sin 2β2 g B. The stone is moving with uniform motion.

The smoothness of the surface. If two systems are in contact and moving. Block is 20 kg.

Friction is the force that resists the motion of one object on another. The force between the two bodies in the normal direction perpendicular to sliding direction. One of the simpler characteristics of friction is that it is parallel to the contact surface between systems and always in a direction that opposes motion or attempted motion of the systems relative to each other.

The frictional force in. Which of the following is not an effect of friction. Calculate the tension in the string.

Which of the following statements best describes how force F arises. Opposes the relative motion between two surfaces in contact. Ignoring the effects of fluid friction what will happen to the object after a downward force is momentarily applied.

A bowling ball colliding with a pin. Start studying the Physics 1. The answer is friction.

B The ball will gain an equal amount of momentum during each second. Friction is a contact force when two surfaces interact. Friction is a type of force that opposes the motion of an object.

When fluid layers are moving relative to each other a type of friction occurs which is known as fluid friction. Ignoring frictional losses determine to what height the water will rise in the tank at equilibrium. The ball rises to a maximum height and then falls back down so that the person catches it.

2 cm D 10 cm. The tank also has a rounded orifice 20 ft below the reservoir surface where the water leaves the tank. The sum of the normal and frictional forces.

This roughness combined with the roughness of the sliding object will give rise to friction. In the diagram. D 10 cm.

Up to 24 cash back Neglect any frictional effects. Which of the following best describes the displacement D of the resultant wave. This type of force acts in the direction opposite to the movement of an object as it slides on a surface.

Only depends on one of the surfaces in contact. The frictional force is greater than the applied force which is acting. Which of the following.

It is impossible to have perfectly smooth surfaces. A baseball flying through the air. Which of the following best describe friction.

Exam 3 flashcards containing study terms like Chapter 8 From the work-energy theorem We can think instead that an object at a certain height has some possible energy that could be released if it is lowered. Find its maximum vertical displacement ignoring effects due to the air. A vibrating guitar string.

Each surface will have its own roughness. A child swinging on a swing. A The ball will gain an equal amount of kinetic energy during each second.

A person throws a ball straight up in the air. B The ball will gain an equal amount of momentum during each second. Further friction is the resistance to the motion of an object as it moves relative to another.
