What else can I help you with?
How is the force you apply by pushing on a rock different from the force of gravity on the rock?
The force you apply by pushing on a rock is due to your muscles exerting force directly on the rock, known as external force. This force is a contact force that can vary in strength and direction. Gravity, on the other hand, is a constant force pulling the rock downward towards the Earth, known as a non-contact force.
A rock is stuck deep in dirt when you pull on the rock to remove it what type of force are you exerting?
You are exerting a pulling force known as tension to remove the rock from the dirt.
Are you presently exerting a gravitational force on the earht?
Yes, I am exerting a gravitational force on the Earth, but it is incredibly minuscule due to my small mass. The force is too weak to have any noticeable effect on the Earth's motion or other objects.
Why do you feel heavier when you go up in an elevator?
Remember, the force of gravity on you is pretty much constant and unchanging. However, the degree to which you 'feel' it depends on whether or not something is pushing back up at you, to balance/resist your weight. If we assume that the elevator is going at a constant speed, then we know that the net force on your body must be zero, since you are not accelerating. Therefore the elevator is still supplying an upward force to resist your weight, and you will still feel heavy. You will only feel lighter if the lift is allowed to accelerate downwards. We can justify all this with equations. If R is the force pushing up against your feet (which makes you feel heavy) then acceleration (a) = (mg - R) / m Rearranging: R = mg - ma Dividing through by mg gives an expression for the proportion of ordinary weight felt: R/mg = 1 - a/g
When you stand on a bathroom scale it displays the blank the earth is exerting on you?
When you stand on a bathroom scale it displays the force the earth is exerting on you, which is your weight. The scale measures the gravitational force between you and the earth such that the reading you see is your actual weight in that gravitational field.
What is a good example of an exerting force?
A person pushing a car or pulling a heavy object are examples of exerting force. This force is required to move or change the position of an object.
Give four examples of a force being exerted?
Five different examples of pushing forces: 1. Pushing a box across the room 2. Sliding a drink down a bar 3. "Pushing" the computer mouse across the mousepad 4. A center pushing a defensive lineman down the field 5. Pushing a car that is in neutral
A child pushing a toy car is an example of what type of force?
The child pushing the toy car is an example of a contact force called a push force. The child is applying a force to the car by exerting pressure on it to make it move.
How are the force of push and pull alike?
Both involve the application of a force to an object. Pushing involves exerting a force away from the body, while pulling involves exerting a force towards the body. Both can cause motion or change in the position of an object.
What are the two forces acting on a person as they move up and down in an elevator and when are these two forces equal and when are they not equal?
When the elevator is still the force of gravity due to your weight pressing downwards on the floor is equalled exactly by the floor pushing you upwards with the same force. When the elevator rises you feel a little heavier, and the elevator is pushing upwards with the same increased force. When the elevator descends you feel that you lose a little weight, and the floor pushes up at you with the equally reduced force, so you descend.
What are 3 examples of exerting a force?
Pushing a door open. Lifting a weight off the ground. Throwing a ball.
What are the key components and forces involved in an elevator free body diagram?
In an elevator free body diagram, the key components are the elevator itself, the tension in the supporting cable, the force of gravity acting on the elevator and its occupants, and the normal force exerted by the floor of the elevator. The forces involved include the tension in the cable, the force of gravity pulling the elevator down, and the normal force pushing the elevator and its occupants up.
Is pushing a box but it doesn't move unbalanced or balanced force?
Pushing a box that doesn't move indicates an unbalanced force. If the force of friction opposing the push is greater than the force you are exerting, the box will not move. In this case, the forces are unbalanced.
How is the force you apply by pushing on a rock different from the force of gravity on the rock?
The force you apply by pushing on a rock is due to your muscles exerting force directly on the rock, known as external force. This force is a contact force that can vary in strength and direction. Gravity, on the other hand, is a constant force pulling the rock downward towards the Earth, known as a non-contact force.
Is kicking push or a pull?
Kicking is a push. When you kick an object, you are exerting a force on it in the direction you want it to move, which is a pushing motion.
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.
If your weight is 140 pounds what size force do you feel pushing back on your feet as you stand on the floor?
This involves Newton's third law of motion; for every force there is an equal and opposite force. If your weight is 140 lbs, then you're exerting 140lbs of force on the floor. In response, the floor is exerting 140lbs of force on you.
