What happens when net force is negative?
Notice that the net force is aimed to the left; so, it is a negative force. Two forces can cancel each other. When two or more forces cancel each other out to create a net force of zero as in the above diagram, we say that the forces on the object are balanced.
In which direction does an object accelerate by the net force?
When there is a net force on an object, it causes the object to accelerate in the direction of the net force; this is not the same as the direction of the motion unless the object is going in a straight line.
How the direction of an object is affected by net force?
The net force on an object is just the sum of all outside forces. So the affect of any non-zero net force is to cause an acceleration in the direction of the force. So the acceleration caused by the net force in this example would be 12 ms2 in the positive direction.
What direction is the resulting acceleration caused by a net force in the up direction?
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Why is a negative force attractive?
Why is negative potential attractive? Force is minus the derivative of the potential, so you have attraction whenever the derivative is positive, which means the potential is increasing, and you have repulsion when it is decreasing.
Can the force be negative?
The answer to the question ” Can force be negative” is simply Yes. Force is a vector quantity and depends upon magnitude and direction. The force depends upon the mass and acceleration of an object. The property of a body to resist a change in the state of rest or state of motion is called inertia.
What property of an object determines how much inertia it has?
Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed.
What force is needed to accelerate a 5kg mass at 10m s2?
So the answer is Fnet=50N .
