## Can an object accelerate with a net force of zero?

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. So acceleration can only occur when the forces acting on an object are unbalanced. Therefore if the net force is zero, acceleration can not occur.

## Is it possible to have a net force of 0?

The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero.

**Can an object still move if the net force is zero?**

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.

### What does it mean if the net force 0?

equilibrium

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 you have force without acceleration?

Newton’s second law states that . We know the mass, but we need to calculate the acceleration. Acceleration is the change in velocity per unit time. Returning to Newton’s second law, we can see that if there is no acceleration, then there is no net force.

**How do you find acceleration with just force?**

The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.

## 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.

## Can we move an object without force?

An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. In the absence of any forces, no force is required to keep an object moving.

**Is there a net force when there is an acceleration?**

There is a net force since there is an acceleration (the slope on a v-t graph means acceleration). Yes! There is a net force since there is an acceleration (the slope on a v-t graph means acceleration). 1. Free-body diagrams for four situations are shown below.

### Why can’t you accelerate when you press the wall?

When you are pressing the wall, the friction between you and the floor is acting in the other direction, making the total force on you to be zero – which is why you’re not accelerating. The same friction, in turn, constitutes force using which you are pushing the floor in a direction opposite the force that is acting on the wall.

### What is the force required to push a mass up an incline?

Mass on Frictionless Incline One of the insights that comes from the setup of this problem is that the force required to push a mass m up a frictionless incline is equal to mgsinθ.

**What angle gives the lowest force when pushing something?**

With this value, a push angle of about 59.9° gives the lowest possible force. This force is lower than pushing it horizontal and lower than pushing straight up. In fact, every angle gives a lower force than pushing it horizontal.
