Why does lifting need more force than pulling?
Lifting an object against gravity requires more force than pulling it along a horizontal surface because you are working against the force of gravity. When lifting, you are fighting against the weight of the object in addition to any other resistance present, such as friction. Pulling, on the other hand, only requires overcoming the frictional force.
What force must a climber work against as he climbs?
The climber must work against gravity as he climbs. Gravity is pulling him downward and he needs to exert force to push himself upward against it.
If 5 newtons of force are pulling on 5 newtons of force?
If 5 newtons of force are pulling against another 5 newtons of force in opposite directions, there will be a net force of 0 newtons, resulting in no movement or acceleration. The forces are balanced and cancel each other out.
What would happen if two people were pulling against each other with forces of 500 newtons and 600 newtons?
The person pulling with 600 newtons of force would overpower the person pulling with 500 newtons of force. The resulting net force would be 100 newtons in the direction of the person with the higher force.
What do you mean by force of friction?
Think of a heavy box lying on the ground with a rope attached for pulling. Until you try to pull the box it doesn't actually resist you. Once you start pulling on the rope, and even if you are unable to move the box, it is as if there is a force pulling against you. This is the force of friction. The friction between the box and the ground sets up this force.
What is the different between push and pull?
When you "PUSH" then you are going against "Gravitational Force" but when you are "PULLING" then you are going against force.
What is the force that works against buoyancy?
The force that works against buoyancy is gravity. Gravity pulls objects downward, while buoyancy pushes objects upward in a fluid. When an object is less dense than the fluid it is in, buoyancy force can overcome gravity and make the object float.
As water moves down though the ground what force is acting against it?
The force of gravity is acting against the downward movement of water through the ground. This force is responsible for pulling the water downwards towards the Earth's center.
When gravity is pulling you downward when you sit is this balanced or unbalance force?
Force equals mass times acceleration, if you are sitting at rest you are not accelerating, so your acceleration is zero. The force is your mass times zero, 75 kg x 0 ms-2= 0 newtons. If the force is zero, this means the force of gravity pulling you down is cancelled out by the force of the chair pushing you up. So the forces are balanced.
If you stand on the ground with the action force of gravity pulling down in which direction is there a reaction force?
The reaction force to gravity is the ground pushing back up against you with an equal force to support your weight. This is known as the normal force.
What if two tug of war teams were pulling at the same force?
It would be the same as if one tug of war team was pulling against a tree.
What force was pulling the anvil down?
The force pulling the anvil down would be gravity.
