You can multiply the amount of torque in Newton-meters by the rotational speed in order to find the power in watts. Another way to look at power is as a unit of speed (m/s) combined with a unit of force (N). If you were pushing on something with a force of 1 N, and it ...
Find the change in kinetic energy of a disk that receives a constant force of 18.6 N as it travels a distance of 0.150 m. A 1,470 kg car is traveling at 25 m/s. The brakes are suddenly applied and the car slides to a stop. The braking force between the tires...
To calculate the force of kinetic friction, the following equation can be used: Fk=μkη μk η The value for the coefficient of kinetic friction will depend on the two types of surfaces coming in contact with one another. These values are usually provided and are seen in a table of coe...
How to Determine the Direction of Kinetic Friction Acting on an Object Step 1: Read the problem and identify all the forces acting on the object. Step 2: Use the definition of kinetic friction as a force that opposes motion to determine the direction of kinetic friction. What...
Does a larger net force always produce a larger change in kinetic energy than a smaller net force? Explain. An object of mass 10.0 kg is initially at rest. A 100 N force causes it to move horizontally through a distance of 6.00 m. Find the change in the kinetic energy of this object...

There's a very basic principle to how we walk: The foot falls heel-to-toe during each step. As your foot lands on the ground, force is brought down through your heel. When you prepare for your next step, you roll your foot forward, so the force is transferred to the ball of your...
Slip limit : 5,699 (##\mu Mg##)Why is the limit so low compared to the brake force ?? There has to be a maximum of 5 bar of pressure for the car not to slip, but according to what I find online, disc brakes tend to work around 30-50 bar, and a lot more if the brake ...
Gasoline engine: The hybrid car has agasoline enginemuch like the one you will find on most cars. However, the engine on a hybrid is smaller and uses advanced technologies to reduce emissions and increase efficiency. Fuel tank: The fuel tank in a hybrid is the energy storage device for the...
