What force present of you lift a pencil off the top of a desk?
The force required to lift a pencil off a desk is the gravitational force acting on the pencil. When you lift the pencil, you are exerting an upward force that overcomes the force of gravity pulling the pencil downward.
When you use a crowbar to lift a large rock you are working against the force called?
When using a crowbar to lift a large rock, you are working against the force of gravity. Gravity is pulling the rock downward towards the Earth, and you are exerting force in the opposite direction to lift it.
Is work done if you lift a brick?
Yes, work is done when you lift a brick against gravity because you are exerting a force over a distance in the direction of the force of gravity. Work is defined as force multiplied by distance in the direction of the force, so lifting the brick requires work to be done.
How does a single pulley make work easier?
A single pulley changes the direction of the force needed to lift an object, making it easier to lift by allowing you to pull downwards rather than upwards. It does not reduce the amount of work needed, but it helps in exerting the force in a more convenient direction.
Is work done on climbing stairs?
Yes, work is done when climbing stairs. Work is defined as force applied over a distance, so when you lift your body against gravity while climbing stairs, you are exerting force over a distance. The energy expended to lift your body is considered work.
How much force are you exerting when you lift a 20-pound dumbbell?
Assuming the dumbbell is suspended at a constant height from the ground and not moving you are exerting 89 Newtons (N). Force (N) = Mass (kg) x Acceleration due to gravity (9.8067 m/s2) 20lb = 9.072 kg 9.072 x 9.8067 = 89 N Leigh

How does a wind lift?
Wind can lift objects by exerting force on them through pressure differences. When wind flows around an object, it creates an area of low pressure on one side and high pressure on the other. This pressure difference can generate lift, similar to how an airplane wing functions.
Is work done on climbing stairs?
Yes, work is done when climbing stairs. Work is defined as force applied over a distance, so when you lift your body against gravity while climbing stairs, you are exerting force over a distance. The energy expended to lift your body is considered work.
How what force is required to lift the 100 pound weight?
To lift a 100 pound weight, you would need to apply a force that is equal to or greater than 100 pounds. This is due to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. So, the force applied must be at least 100 pounds to overcome the force of gravity acting on the weight.
Does a boy holding a suitcase in his hand exert force?
Yes he exerts a force which equals to the weight of the suitcase. So the suitcase is at rest in his holding
What two things you do that use force?
Pushing a heavy object across a room requires force to overcome friction and move the object. Lifting a weight off the ground involves exerting force to counteract gravity and lift the object.
How many pounds of force does it take to lift a 100 pound man buried under 1 foot of corn?
800
How much should a 12 year old boys biceps curl?
Hmm well lets see at my age of 14 I can about lift a 20 25 Pound dumbbell with a single arm then again I am no body builder so Im guessing maybe if you worked out a bit a few push-ups here and there probably a 15 or 20 pound dumbbell but just a guess
