Give five examples of acceleration?
1) To move a standing object we need to apply force and to stop a moving object we need to apply brakes. 2) Car
If an object is accelerating does Newton's third law apply?
Basically, Newton's Third Law ALWAYS applies.To accelerate an object, you need to apply some force to it. There MUST be a counterforce, from the object back to the object that pulls or pushes it.
How the acceleration of a moving object can be increased?
In order to increase the acceleration of an object, you need to increase the net force applied to the object.
What is needed for work to be done on an object?
As a simplified explanation, work = force x distance. You need to apply a force over a certain distance, for work to be done.
Why must a force be exerted to cause an object to move on a curve path?
Newton's 1st law of motion: an object will continue on its course at the same speed and direction, if the net force acting on the object is zero. Hence, if you don't apply any net force on the object, its direction and speed will not change (it will not move on a curved path). If you want the object to change direction, you need to apply a net force away from the direction of travel (the net force is pointing at a non-zero angle with the direction of travel).
How do you find out if a force is balanced or unbalanced?
Its easy....To balance force you need to apply an equivalent force in the opposite direction....Example:If a force of 20N acts on a body along the North, you should apply 20N along the south......simple.......
What does an object need in order to have gravity?
There is a force of gravity between every pair of masses. So any object with mass is attracted to every other object with mass.
What do you need in order to have a Force greater than zero acting on an object?
Push it, or pull it. You may have to push hard enough to overcome a force of friction.
How much force is needed to move an object?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
What tool erasures the force of gravity on an object?
There is no such tool. If you need for the object to move opposite to the force of gravity on it, then you just have to come up with a force that's greater than the force of gravity, and apply it in the opposite direction. That certainly sounds complicated, but it's exactly what you do with your arm muscles when you want to pick up a book, or with your leg muscles when you need to walk up some stairs.
Do you need force to make an object moving in a circle?
Yes you do. You need a force that always attracts the object toward the center of the circle. It's called a "centripetal force".
