5) The baseball player does 1234 Joules of work when hitting a baseball into left field. Assuming the baseball landed 100 meters away from home plate, how much force did the player use to hit the ball?
Force-Distance graphs If the force is non-uniform then the formula W = F × d does not apply. Instead, we present the information as a force-distance graph and calculate the area beneath the graph to find the work done by the force. Recall the other “area under a graph”, which is the force-time graph that gives the impulse of a force.
use cosine theta to get the correct force vector. Work is measured in a unit called, "Joules" or J for short. Power = (Energy or Work) / time. Power is measured in Watts (W). One watt is just one Joule/sec . 1. A 60 kg box is lifted by a rope a distance of 10 meters straight up at constant speed. How much work is required to lift the box ...
Work & Energy Word Problems Calculating Work. Work has a special meaning in science. It is the product of the force applied to an object and the distance the object moves. The unit of work is the Joule (J) Work = Force x Distance W= F x d Work = joules (J) Force = newtons (N) Distance = meters (m) 1.
If a small machine does 2,500 joules of work on an object to move it a distance of 100 meters in 10 seconds, what is the force needed to do the work? What is the power of the machine doing the work?
The definition of work done is given by the product of force ( ) and the distance moved in the direction of force ( ). The unit of work done is in Joules (J), which is equivalent to Newton metres (Nm). Example 1: A van is driven along a straight horizontal road.
If 150 Joules of work is needed to move a box 10 meters, what force was used? B. Fill-in-the-blank: 1. _____ is done when an object moves through a distance because of a _____ acting upon the object. 2. When calculating work, you should use the formula: work = force X _____. 3. The SI unit for work is the _____. It is represented by the letter ...
