What Forces acting on a stationary car?
Normal contact force (upwards) Gravity/Weight (downwards) Equal to NCF
Is gravity the force applied up or down on an object?
Gravity pulls things downwards, so it is pointed downwards. If an object is resting on something (like a book resting on a table) an equal force will point upwards and that force is known as the normal force.
When does an object not move downwards under the effect of gravity?
On every object on earth, earth exerts a force on it which is equal to the weight of object. When we throw a object it earth exerts force on it and it came downwards but if we throw it with escape velocity then it will not move downwards.
When you push downward on earth to make a pole vault does earth exert an equal force on the pole?
Yes, otherwise the pole would move downwards
What kind of forces does NOT change the motion of an object?
Equal and opposite forces. Imagine 2 people pushing a car, one at the front and one at the back. If they are both pushing with the same force, the car will not move.
What Forces acting on a stationary car?
Normal contact force (upwards) Gravity/Weight (downwards) Equal to NCF
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 is the force exerted upwards from the ground?
In mechanics, the force exerted upwards by the surface that a body sits on is equal and opposite to the force exerted downwards by that body and is referred to as the Ground Reaction Force (GRF) or simply Reaction.
Is gravity the force applied up or down on an object?
Gravity pulls things downwards, so it is pointed downwards. If an object is resting on something (like a book resting on a table) an equal force will point upwards and that force is known as the normal force.
How powerful is air resistance?
aprroximately 9.81 Newtons as the upwards and downwards forces must balance and the acceleration of free-fall is 9.81 newtons therefore the air resistance must be equal.
What force is acting when you are sitting on a chair?
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
What newtons law would carrying a backpack be an example of?
The third: every action has an equal and opposite reaction (in the simplest terms). The backpack is exerting a downwards force on the person, and the person balances this by exerting an upwards force on the backpack. If the forces weren't equal, the backpack would either fall to the ground or float above the person.
How big is the force from the spring compared to the downwards force?
Equal and opposite (Newton's law)
When does an object not move downwards under the effect of gravity?
On every object on earth, earth exerts a force on it which is equal to the weight of object. When we throw a object it earth exerts force on it and it came downwards but if we throw it with escape velocity then it will not move downwards.
Normal force is supplied by what?
A surface pushing up, equal and opposite to a force pushing against it
What two forces act on the paper cup as the repeling magnets contend to keep it in this position?
Gravitational force (gravity) acting downwards and the normal force of the table acting on the cup upwards. These two forces when added together equal zero. Therefore, there is no movement. They keep that cup and its contents in position.
What is two numbers that equal two thousand two hundred and sixty-eight?
There's an infinite amount of such two numbers. Presuming you want only natural numbers, you could just count one of them upwards and the other one downwards starting with 1 and 2267: 2, 2266; 3, 2265; 4, 2264 etc.
