How much force exert when lifting an object?
The force exerted when lifting an object depends on the mass of the object and the acceleration due to gravity. The formula to calculate force is F = m * g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity (approximately 9.81 m/s^2 on Earth).
What minimum downward force needed to lift the 120 Newtons weight?
No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
How much mass does a celestial object have to have to exert gravitational force?
There is no minimum mass at which point an object (celestial or otherwise) begins to have a gravitational force. Any object with mass has an associated gravitational force. The magnitude of that force is proportional to to the mass of the object - lots of mass results in lots of gravitational force; little masses result in only little gravitational force.
What is the advantages of a simple machine?
output force divide by the input force is the mechanical advantage of a simple machine.The output force is the force that is exerted by the machine on an object, and the input force is the force that we exert on a machine.
If you lift 1600 meters straight up how much work did you do?
To calculate the work done when lifting an object, you can use the formula: work = force × distance. The force required to lift an object is equal to its weight, which is mass × gravity. So, you would need to know the mass of the object to calculate the work done when lifting it 1600 meters.
If the gravity exerts 15 N and there is 10 N of friction how much force will Jim need to exert to move it?
Jim will need to exert at least 25 N of force to overcome both gravity and friction and move the object. This is calculated by adding the force of gravity (15 N) and the force of friction (10 N).
Why are not attracted to the wall by gravitational force?
Humans are not attracted to walls by gravitational force because walls do not have sufficient mass to exert a noticeable gravitational pull on us. The force of gravity is proportional to the mass of an object, so walls, being much less massive than the Earth, do not exert a significant gravitational force on us.
What determine how much gravity something has?
The amount of gravity something has is determined by its mass and how close it is to other objects exerting gravitational force. The more massive an object is, the more gravitational force it can exert, and the closer two objects are, the stronger the gravitational force between them.
Why is it that your weight change from place to place but your mass stays the same?
Your mass is how much matter you are made up of. Your weight is how much force you exert on your surroundings. If the force of gravity is greater or weaker, then your constant mass will exert more, or less force on the surroundings, ie, your weight will be different.
How much work is done in lifting a 50kg object to height of 5m?
The work done in lifting a 50kg object to a height of 5m is 2450 Joules, calculated using the formula: Work = force x distance x cos(theta).
How can you exert force on an object but not do any work on it?
Centripetal force is needed to keep object to go in circular motion but no work will be done by it. (Not my answer. analogdino) To answer the original question, just don't let the object it move! Work is force times distance moved. BTW, it's "exert" not "excerpt".
How much force is needed to accelerate an object twice as fast?
To accelerate an object twice as fast, you would need to exert twice the force. This is because force is directly proportional to acceleration, as defined by Newton's second law, F=ma. So if you double the acceleration, you must double the force.
