Work Practice Problems Worksheet #1 ANSWER KEY 1) Amy uses 20N of force to push a lawn mower 10 meters. How much work does she do? Work = Force X Distance Work = 20N X 10m Work = 200 J 2) How much work does an elephant do while moving a circus wagon 20 meters with a pulling force of 200N? Work = Force X Distance Work = 200N X 20m Work = 4000 J
You have just derived the distance formula! Note that given any two points with coordinates (x1, y1) and (x2, y2), the distance, d (also called Euclidean distance), between them is given by the formula below. formula to compute the distance between the following points: 1. (1,1) and (3,7) 2. (-1,5) and (2,9)
Calculate the time it takes to travel a distance of 672 km at a speed of 96 km/h. 15. A beetle travels at a speed of 0.09 m/s, it travels a distance of 1.08 m before it is caught
Help students learn the difference between distance and displacement by showing examples of motion. As students watch, walk straight across the room and have students estimate the length of your path.
Force, Distance, and Work 1. What force acts on the object when it has been moved 4.0 m? 2. How far has the object been moved when the force on it is 200.0 N? 3. Explain the shape of the line on the graph. 4. Which formula is used to calculate work when a constant force is exerted on an object? 5.
