# What is a balanced force?

## What is a balanced force?

When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . a stationary object stays still. a moving object continues to move at the same speed and in the same direction.

## What is the force if there is no acceleration?

Acceleration is the change in velocity per unit time. Since the velocity does not change from one moment to the next, then there must be no net acceleration on the object. Returning to Newton’s second law, we can see that if there is no acceleration, then there is no net force.

Why does force equal mass times acceleration?

Newton found that an unbalanced force is required to change an object’s velocity. Newton’s Second Law of Motion defines force in this way: Acceleration is produced when a force acts on an object. The 2nd law provides the definition of force: F = m a, where F is force, m is the mass, and a is acceleration.

How to calculate force by mass and acceleration?

Here are few force examples to learn how to calculate force by applying mass and acceleration. Let us consider the problem: Find the force of an object with mass (m) as 600 kg and acceleration as 50 m/s^2 We can calculate force the using the given formula. = 600 x 50 = 30000 N Hence, force of the object is 30000 Newtons.

### When do you use the equation for acceleration?

This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known. The equation for acceleration can be rewritten as F = m × a to calculate the net force acting on an object when its mass and acceleration are known.

### How is acceleration related to the second law of motion?

An object acted on by an unbalanced force will accelerate in the direction of that force, in direct proportion to the strength of the force, and in inverse proportion to the mass of the object. Newton’s second law is best described with a mathematical equation that relates three variables, force, acceleration and mass, to one another.

How to calculate the acceleration of an object in free fall?

An object of mass 30 kg is in free fall in a vacuum where there is no air resistance. Determine the acceleration of the object. Since it is in free fall and is falling due to the force of gravity…..the acceleration will always be 9.8 m/s2 13.
