# How do you solve retarding force?

## How do you solve retarding force?

A retarding force causes the acceleration of an object to be negative. In \$F = ma\$ , where F is the resultant force, the force acts against the direction of the object’s current velocity is the retarding force. Formula used: \$F=ma\ \$ and \$F=ma\;,a=\dfrac{v}{t}\$.

What is retarding force example?

1. retarding force – the phenomenon of resistance to motion through a fluid. drag. resistance – any mechanical force that tends to retard or oppose motion. sonic barrier, sound barrier – the increase in aerodynamic drag as an airplane approaches the speed of sound.

### What is the formula of retardation?

a = Change in velocity/Time taken So, you can get a negative acceleration value in the case of v

Is retarding force negative?

Yes, Retarding force is always negative as the direction of force and the direction of motion is opposite to each other, making 180° between them.

#### Where can I find retarding force in Class 9?

1. Retarding force, F=50N.
2. Mass of the body, m=20kg.
3. Initial velocity of the body, u=15m/s.
4. Final velocity of the body, v=0.

Why is friction a retarding force?

When an object moves over the surface of another object, its motion is always opposed by a retarding force that resists motion. This retarding force is called friction and it always acts in the direction opposite to the motion of the object.

## Why is it called retarding force?

Forces that resist relative motion (like air resistance or friction) are called ‘retarding forces’. No force can in general ‘resist motion’ make things stop moving because it doesn’t mean anything to say whether something is moving or not, only whether it’s moving relative to something else.

Is retarding force negative or positive?

A retarding force, is simply put, the force that causes the acceleration of an object to be negative.

### Is retardation a physics?

Retardation is nothing but a negative acceleration. The velocity of the body may either increase or decrease. The change in velocity is known as acceleration. If the velocity of the body increases, acceleration is said to be positive.

What is the symbol of retardation?

Answer:There is no symbol for retardation. It is written as ‘retardation’ only.

#### Is retarding force positive or negative?

∴ When a force retards the motion of a body, the work is done by the force during retardation is negative.

What is meant by term retardation?

Retardation is often used to describe problems in human mental development that result in a lack of intelligence or other kinds of physical or learning delays. You can use retardation to describe other kinds of slowness or delays too, including simply a decrease in speed.
