The work done while moving the lawn mower the given distance was 13 500 J. For a vector that is represented by the coordinates (x, y), the angle theta between the vector and the x-axis can be found using the following formula: arctan(y/x). If he pushes the lawn mower 30.0 m, how much work has been done to move the mower?Īnswer: The force is at an angle of 60.0° with respect to the movement. The hypotenuse (force or velocity) and the angle is used to calculate the vertical and horizontal. The force he is applying to the handle of the lawn mower is angled down, 60.0° from the horizontal plane. It can be calculated by expressing in right angled triangle. The work done by the tractor to move the wagon the given distance was 12 000 000 J, which can also be stated as mega-Joules: 12.0 MJ.Ģ) A man is pushing a lawn mower across his yard. Find how much work was done by the tractor to pull the wagon.Īnswer: The force and the movement were in the same direction, so the angle between them is 0°. The force acted in the same direction as the movement. The force exerted on the wagon to move it that distance was 12 000 N. Apart from that, all these calculators show you step-by-step calculations by using certain physics formulas. The calculator-online gives basic to advance level physics calculators that will assists you to solve the different complex problems. You can use physics to calculate how much work is required, for example. Don’t fret, our free online physics calculators helps to calculate the different physics related terms. The angular work is equal to the product of torque and the total. Calculate the tipping angle for the three objects considered in Activity 2. 1) A tractor pulled a wagon full of hay a distance of 1000 m. If you apply force at an angle instead of parallel to the direction of motion. The angular work in physics is the net work done on a body to rotate it about a fixed axis. Our physicists’ team constantly create physics calculators, with equations and comprehensive explanations that cover topics from classical motion, thermodynamics, and electromagnetism to astrophysics and even quantum mechanics. where g is the acceleration due to gravity, usually taken to be 9.81 ms2 at.
