= 0, plug in values to get answer P = Fd / t. Since there is no distance moved, the power is zero This is a conservative situation so the total energy should stay same the whole time. It should also start with max potential and min kinetic, which only occurs in choice C Stopping distance is a work-energy relationship.

AP1 Rotation Page 1 1. A 50-kg boy and a 40-kg girl sit on opposite ends of a 3-meter see-saw. How far from the girl should the fulcrum be placed in order for the boy and girl to balance on opposite ends of the see-saw? Answer: 1.67 m In order for the children to balance, the net torque about the fulcrum must be zero, resulting in no angular ... 4) How is it used? What questions does it help us answer? Torque is used through wrenches, force, levers, and lever/moment arms. Torque can help to measure forces and how big a force is, as well as being used to quantify effects. It helps us answer how much rotational force is being applied to an object on a pivot, door, or lever arm. physics webquest torque answer key.pdf FREE PDF DOWNLOAD NOW!!!

torque (rotational force) to move them. Robots can be heavy, too. You need to make sure the motor and the gear ratio produces enough torque to move them. And motors are rated in torque! If you make a mistake figuring out the torque, it is easier to make changes on little robots that you snap together than big robots that you have to weld together.

What three factors affect the torque created by a force relative to a specific pivot point? 4. A wrecking ball is being used to knock down a building. One tall unsupported concrete wall remains standing. If the wrecking ball hits the wall near the top, is the wall more likely to fall over by rotating at its base or by falling straight down? Explanation: . The net torque on the pulley is zero. Remember that , assuming the force acts perpendicular to the radius.Because the pulley is symmetrical in this problem (meaning the r is the same) and the tension throughout the entire rope is the same (meaning F is the same), we know that the counterclockwise torque cancels out the clockwise torque, thus, the net torque is zero. Rotational Energy and Angular Momentum Conservation In this training set, you will learn how to use conservation of rotational energy and angular momentum to solve for the rotational motion of objects and systems: KE r = ½ I COM ω 2 L = r × p = Iω KEr = L2/2I COM Note that KE r is a scalar quantity, and measures rotation about the center of ...

Worksheet: Torque. Name_____ 6. To solve torque problems, diagrams must be drawn. Complete the diagram for. each situation described below. Draw a bold dot for the pivot point. Draw and. label each force vector. (Bars, boards, etc. are considered uniform unless. stated otherwise.) Label each torque as "cw" or "ccw". a. Two ropes, having tensions T 2 and T 3, support a uniform 100-N beam and two weights.If the right weight has a mass of 25 kg and T 2 has a tension of 500 N, calculate the tension in T 3 as well as the mass of the unknown weight.

<this does seem quite large! – check answer> b) The beam will now pivot about point B. Are there two torques or three? Does the rope still pull downwards when the beam is about to tilt? Assume yes. The forces are the same as in part (a) (mass A is unknown), but the distances have changed. ( we will find the 3 distances again:

If the force is applied directly perpendicular to the the lever, as shown in the diagram, what is the magnitude of the torque acting the lever? Torque = Force * lever Since we know both the amount of force and the length of the lever, figuring torque out become very easy for us. Torque = 5.0 N * 2.0 m Torque = 10 N*m Practice questions in the fundamentals of physics while you review topics from classical dynamics to modern quantum mechanics with Albert's AP® Physics 1 exam prep. Without providing a numerical answer to your question, to do so would help nobody: It would help to first draw a 'free-body-diagram', doing so will help you visualise the forces acting on the pole. You need to calculate the moment at the hand 1m from the end, this is your pivot, from the force exerted by the mass of the pole. Rotational Motion and Torque Powerpoint: ...
