Can you have a net force of zero?

Newton’s First Law is the law of inertia. An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity. Now we come to the case when the net force on an object is not zero.

Is the work 0 if the net force is 0?

The correct answer is B) 0 joules. Think of work done as a measure of displacement in the direction of force times force. If the displacement is perpendicular to the direction of force or if it is zero then work done is equal to zero.

In which situation is the net force become zero?

Net force becomes zero when the forces in opposite direction are equal.

What it net force can it be zero if yes then give an example?

If yes, state the conditions that must be placed on the magnitude and direction of the velocity. A raindrop falls down with a constant velocity. The weight of the drop is balanced by the up thrust and the velocity of air. The net force on the drop is zero.

What is work done when force is zero?

Work done by a force is zero if the direction of force and displacement are perpenddicular to each other or if the displacement is zero.

Can an object with zero net force acting on it be moving explain?

Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving. So, yes, the object can be moving when there is no force applied to it.

Can the impulse of a force be zero even if the force is not zero explain why or why not?

Yes. The term “impulse” is a quantity that is equal to the change in momentum and it is also equal to the applied force multiplied by the…

What is a zero net force?

If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium. When an object is in equilibrium, then two things can be true: either the object is not moving at all, or the object is moving with a constant speed.

Can net force be negative?

Forces can be positive or negative. Actually, forces which are aimed to the right are usually called positive forces. And forces which are aimed to the left are usually said to be in a negative direction. Notice that the net force is aimed to the left; so, it is a negative force.

What do you mean by zero work?

ZERO WORK:The work done is said to be zero work when force and displacement are perpendicular to each other or when either force or displacement is zero. example: When we hold an object and walk,the force acts in downward direction whereas displacement acts in forward direction.

What happens to work done when net force is zero?

The net work done by all forces acting on an object is equal to the kinetic energy change of that object. If the net work is zero, that means there is no kinetic energy change. That means that once the object being lifted is in motion, it moves up at constant speed.

What will an object do when the net force is not zero?

It could be the sum of two forces or more than two forces. If only one force acts upon an object, then this one force would be the net force. If the net force on an object is zero, then the object experiences no velocity change. If the net force on an object is not zero, then the object will show a change in velocity.

When does an object have a net force of zero?

If the net force acting on an object is zero, then it means that the object’s velocity is constant and the object isn’t speeding up or slowing down. That is, there is no acceleration on an object with zero net force.

What happens when net torque is zero?

A nonzero net torque will result in an angular acceleration. When the nut starts to rotate, from stationary, it is being accelerated, so there is a net torque. But very soon it’s rotating at a steady rate, so the net torque is back to zero. The torque you continue to apply is equal to the dynamic friction.
