Work = (force) x (distance) = 7 x 2.4 = 16.8 joules
Length or distance is measured in meters.
Divide this distance - 38 meters, is it? - by the distance of a light-year (about 9.5 x 1015 meters).
say g=10,mass =10 kg , force up =1000n force down = mg = 10*10=100n force up = 1000n, net force = 900 n up force of 900 n acting on 10kg, using a=f/m , a=900/10, a = 90 m/s^2 you have to include a time in the data, lets say 10s then s=(a*t^2)/2 , s=(90*100)/2 , s = 4 500 meters
Let's see. First.....,F = mam = F/am = 4 N/9.8 m/s2= 0.408 kilograms----------------------m = 5 N/9.8 m/s2= 0.510 kilograms-----------------------------secondly......,PE = mghPE = (0.408 kg)(9.8 m/s2)(3.0 meters)= 11.99 Joules==============A 4 Newton object lifted 3 meters gains more potential energy.
No, because a newton is a measurement of force. You can only convert units that measure the same object. For example you can convert meters to feet because they are both measurements of distance.
question 24 on penn foster is C.
700 x 4 = 2,800 newton-meters = 2,800 joules
use the formula W = mgs W stands for work done in joules m stands for mass of the object g stands for gravity s stands for the distance the object is lifted W = mgs W = 78kilograms•9.8m/s2•6meters W = 4586.4 J (joules) answer would be 4,586.4 J
78*6*9.8 N = 4586.4 N
Length or distance is measured in meters.
I believe that when you say 'lifted through', you mean lifted to a height of 10m. If so, the amount of work is such: Work= Force x Distance which have the units (Joules = Newtons x meters) When the object is lifted, it increases in its potential energy. The equation for this is: Potential energy = mass x gravitational force x height = 4.5 x 9.81 x 10 =441.45 Joules As 1 joule = 1 newton x meters and we have 441.45 Joules, 441.45 joules of works is done! :D
The potential energy gained by the object is 1,000 Joules. Potential energy is calculated using the formula PE = mgh, where m is the mass of the object (10 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height the object is lifted (10 meters).
To calculate the amount of energy (joules) required to lift an object, you can use the formula: Energy (joules) = Weight (Newtons) x Distance (meters) x gravitational constant (9.81 m/s^2). Simply multiply the weight of the object by the distance it is lifted and the value of gravity to determine the total energy in joules.
The lever effect for lifting refers to using a lever to reduce the amount of force needed to lift a heavy object. By increasing the distance between the pivot point (fulcrum) and the object being lifted, less force is required to lift the object. This principle is based on the relationship between the distance from the fulcrum to the applied force (effort) and the distance from the fulcrum to the object being lifted (load).
If an object does not move, no work is performed. Work is performed by a force acting through a distance.
If you have lifted the object 5m off the ground, you would have pulled 10m of rope through the pulley system. This is because as the object gets lifted, the rope length on both sides of the pulley decreases by the same amount.
Arm is the example of 2nd class lever.
