Well if we use work = force * distance we have the distance but not the force. We have to use another equation f=ma (force = mass*acceleration) where the acceleration is gravity (9.8 m/s or 10 if you are rounding). Not using rounding:
m=10
a=9.8
therefore 10*9.8=98N=force
We then input that into our work formula:
force = 98
distance = 5
therefore 98*5 = 490J = work
without rounding that would simply be 500J
Hope this helps!
The work done by gravity on the 10kg object going 5m up is given by the equation: work = force x distance x cos(theta). In this case, the force would be the weight of the object (10kg * 9.8 m/s^2), the distance is 5m, and theta is 180 degrees (as the force of gravity is opposite to the direction of motion). Calculating the work done would give you the answer in joules.

How much work does gravity do on the apple if it falls 6m?
Gravity does work equal to the change in potential energy of the apple as it falls. The work done by gravity can be calculated by multiplying the force of gravity (9.8 m/s^2) by the distance the apple falls (6m). The work done by gravity on the apple falling 6m is approximately 294.24 Joules.
How much work is done against gravity when lowering a 16 kg box 0.50m?
The work done against gravity is calculated using the formula: work = force x distance. In this case, the force against gravity is the weight of the box, which is mass x gravity. So, work = (16 kg x 9.8 m/s^2) x 0.50 m = 78.4 J.
When is work said to be done against the force of gravity?
Work is said to be done against the force of gravity when an object is moved vertically upwards, against the force of gravity, over a certain distance. In this case, the force applied must be greater than the force of gravity acting on the object for work to be done against gravity.
What factors affect the ability of gravity to do work?
The factors that affect the ability of gravity to do work include the distance the object falls, the mass of the object, and the presence of other forces that may oppose gravity, such as friction or air resistance. The work done by gravity is determined by the height through which the object falls and the force of gravity acting on the object.
Is walking is the work against gravity?
Yes, walking involves working against gravity because we must lift our body weight with each step. Our muscles work to counteract the force of gravity pulling us downward to move us forward.
How much work is done by gravity as the riders are lifted to a height of 60 meters?
Gravity does not lift. The force is doing the work by lifting the riders. When the riders come down from the 60 meter height, then gravity will be at work.
How much work does gravity do on the apple if it falls 6m?
Gravity does work equal to the change in potential energy of the apple as it falls. The work done by gravity can be calculated by multiplying the force of gravity (9.8 m/s^2) by the distance the apple falls (6m). The work done by gravity on the apple falling 6m is approximately 294.24 Joules.
Does peristalsis work against gravity?
Yes, peristalsis will work against gravity.
Why does a rocket need such a big engine?
So that it can escape Earth's Gravity. The rockets work by burning so much fuel that they can overpower Earth's gravity.
How much work is done against gravity when lowering a 16 kg box 0.50m?
The work done against gravity is calculated using the formula: work = force x distance. In this case, the force against gravity is the weight of the box, which is mass x gravity. So, work = (16 kg x 9.8 m/s^2) x 0.50 m = 78.4 J.
How will things work with no gravity?
If there was no gravity nothing would be stationary. One example is that everything would float right off the planet and keep going forever. Another example is that if you threw a baseball, it would not slow down or stop, it would keep going.
How much work does the force of gravity do on a 5.45-kg bowling ball that falls a distance of 0.755m?
41.1j
What is powered by earth gravity?
Earth gravity powers anything that falls, doing work on it equal to its weight multiplied by the distance it falls, and giving it that much kinetic energy.
How much work must be done on a 10kg bicycle to increase its speed from 2 M's to 3 M's?
Work done = increase in kinetic energy ie 1/2 * 10 * (3+2)(3-2) [recall a2 - b2 = (a+b)(a-b)] Hence work done = 25 joule.
How does gravity work in the height?
as we go up gravity decreases
What did Issac newton explain?
Sir Issac discovered gravity and did much work concerning optics and the nature of light.
If an engine must do 500joules of work to pull a 10kg load up to a height of 4 maters what is the efficiency of the engine?
10Kg X 9.81 m/s^2 = 98.1 newtons 98.1N X 4m = 392.4 joules 392.4J/500J X 100% = 78.48% efficient
