What was Isaac newtons 2 rule?
The second law is about how the force affects the motion. A relatively small force could make, say, a tennis ball accelerate a lot (e.g. changing its direction completely), but could not make the motion of, for example, a truck change very much. This is because the mass of the objects are very different. Similarly, if two objects had the same mass, a large force would change the motion a lot, where as a small force not so much. So the change in motion depends on the size of the force and the mass of the object.
Can an object have a non zero force and have constant kinetic energy?
an object can have a non zero force acting upon it if and only if the sum of all of the forces on the object is still equal to zero. The sum of the forces is equal to mass times acceleration. If an object is accelerating, then it does not have a constant KE therefore the sum of the forces must be equal to 0 so that acceleration is also equal to zero. For instance, take the case of an object falling through the air. Initially, the force of gravity is accelerating the object downward and it is gaining KE. After some time, this object will reach terminal velocity. At this point, the resistance force of the air on the object negates the force of gravity and the sum of the forces is equal to zero. The object now falls at a constant velocity and in turn also a constant KE. It is still being acted upon by the force of gravity and the resistance force but these forces are canceling each other out. =============================== I don't like to delete an answer that somebody put a lot of effort into, and supervisors don't like it when I become plainly uncomplimentary. So all I can say is: Use the above answer at your own extreme peril, and far better to ignore it. Especially the 1st and 3rd sentences.
Can centrifugal force be balanced by coulomb force in an atom?
It can, but other forces (like the Strong Nuclear Force) also balance out the electromagnetic force. This gets into quantum mechanics, and the centrifugal force doesn't really apply a whole lot.
Why the brightest object in the night sky if it does not make its own light?
The moon is the closest heavenly body to the earth and because of its relatively high albedo it reflects a lot of the light falling on it hence it is the brightest object in the night sky. Similar reasons also apply to Venus, which is also a very bright object.
What is the force that changes earth's crust?
The force of changing earth's crust is...... that the earth's crust is a lot thinner
Why does it take more force to accelerate a more massive object?
A force will not increase or decrease an acceleration. If the force is constant, it will cause a constant acceleration. It may increase or decrease the speed. The change of velocity - for the same force - is the same, whether the speed is increasing, decreasing, or just changing direction.
Why is it that an object with momentum is hard to stop?
An object with momentum is hard to stop because momentum is a measure of how much motion an object has. When an object is in motion, it has momentum, and stopping it requires applying a force in the opposite direction. The greater the momentum of an object, the more force is needed to bring it to a stop.
What a small mass with a lot of force applied?
The object accelerates.
How are force and momentum related?
Force is the rate of change of momentum. When a force is applied to an object, it causes the object's momentum to change. The greater the force applied, the greater the change in momentum experienced by the object.
What is an example of being opposed by static friction?
When you move a heavy object, you must apply a lot of force before the heavy object begins to move. This resistance you feel while the box is NOT moving is static friction. Static friction opposes movement in an initially non-moving object.
What is an object that you use a lot of force on it to move it?
A door is an object that often requires a significant amount of force to open or close, especially when it's stuck or jammed.
Do you think you need a lot of force to change an object's inertia?
No, changing an object's inertia does not necessarily require a lot of force. Inertia is an object's resistance to changes in its state of motion, and the amount of force needed to change it depends on the mass of the object. Smaller forces can change the inertia of light objects, while heavier objects may require more force.
What allows you to hold things?
The force of your hands holding on two sides of the object you wish to hold. Although the gravitational force that is pulling the object downward is great; the force your hands are pressing onto the sides of the object is a lot greater. You will find that if you don't hold an object as tightly (decrease the force) it may drop. This is because the gravitational force increases.
How is the gravitational force on objects measured?
mass by acceleration, as in a large object that spins quite fast, like the earth, will have a lot of gravitational force.
How does mass affect distance when the force applied is the same?
well think of it like having a small object with little mass then a large object with a lot of mass. Hitting the big object takes more force to make it move and the little object does not take nearly as much force to make it move. i hope this helped!
The force of gravity on a 4kg object is twice that on a 2kg object Why does the 4kg object not fall with twice the accleration?
The reason that a heavier object does not fall faster even though there is more gravitational force on it is because it has more mass, and more energy is required to accelerate the greater mass. A small mass doesn't need a lot of force on it to accelerate it. It's "light" in weight. But a heavier one needs more force on it to accelerate it equally. Want a heavier object to accelerate the same as a lighter one? Apply more force. Gravity does that. Automatically. Think it through and it will lock in.
What force is pulling up an object when gravity is pulling the object down?
Gravity is the force of attraction between matter. When an object exerts gravitational force on another object, the other object also 'pulls' the first object. These force vectors are equal and opposite. In the example of a person being pulled towards a planet, the planet is also being pulled towards the person with the same force between them. The planet just has a lot more mass and accordingly accelerates a great deal less. There is no force "pulling up", but the strength of your legs are pushing up. (the equal and opposite force required for stability).
