## What is distance in physics example?

## What is distance in physics example?

The distance of an object can be defined as the complete path travelled by an object. E.g.: if a car travels east for 5 km and takes a turn to travel north for another 8 km, the total distance travelled by car shall be 13 km.

## Is it possible that distance not zero but displacement is zero?

Yes, displacement can be zero even if the distance is not zero. For example, when a body is thrown vertically upwards from a point A on the ground, after sometime it comes back to the same point A.

## What is SI unit of retardation?

The SI unit of retardation is the same as that of acceleration, that is metre per second squared (m/s2).

## What is positive and negative velocity?

If we’re moving along a line, positive velocity means we’re moving in one direction, and negative velocity means we’re moving in the other direction.

## Can distance be zero give example?

No. For example, a car travels from point A to B and then comes back. Suppose AB=5m. In this case, displacement travelled is 10m, while the distance is zero.

## How is velocity zero?

While this might result in a frenzy of activity, it would result in a zero velocity. Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity.

## What is the difference between distance and displacement?

distance is how far away something has travelled from another object, while displacement is how far something is from the other object. Displacement is a vector quantity, unlike distance.

## Why retardation is called negative acceleration?

If the velocity of the body increases, acceleration is said to be positive. Similarly, if the velocity decreases, the acceleration is said to be negative. Retardation is acceleration with a negative sign. Or the negative value of acceleration shows that the velocity of a body is decreasing.

## Can average speed be zero?

The average speed cannot be zero unless the body is stationary over a given interval of time. Average speed is the ratio of the total distance travelled by a body to the total time interval taken to cover that particular distance.

## Does deceleration have a negative sign?

Deceleration always refers to acceleration in the direction opposite to the direction of the velocity. Deceleration always reduces speed. Therefore, it has negative acceleration in our coordinate system, because its acceleration is toward the left.

## Is it possible that displacement is zero but?

Yes, it is possible that displacement can be 0 but distance is never 0. but if you see the displacement , it is 0 because your starting point is A and ending point is also A . And reverse of it is not possible because distance can never be 0 if you travel from one point to another.

## What is positive and negative direction?

A positive velocity simply means that the object is moving in the positive direction, as defined by the coordinate system, while a negative velocity means the object is traveling in the other direction.

## Is there a negative distance?

Distance cannot be negative, and never decreases. Distance is a scalar quantity, or a magnitude, whereas displacement is a vector quantity with both magnitude and direction. It can be negative, zero, or positive.

## What is negative direction?

An object which moves in the negative direction has a negative velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a positive acceleration).

## How can displacement be negative?

Displacement can be negative because it defines a change in position of an object while carefully monitoring its direction. Then you walk back towards your original location in the −h opposite direction.

## What is positive position?

Positive positioning is delivering a message in a positive way and in such a way that minimizes a negative reaction. Positive positioning is easy to do when you focus on three things. First, maximize positive language while minimizing negative words. It’s best to stay away from negative words when handling problems.

## Can distance be negative physics?

Distance is the total length traveled by an object. Because it is a scalar quantity, it can never be negative.

## Why displacement can be zero but distance Cannot?

Yes , displacement can be zero but distantce because displacement has both direction and magnitude while distance has only magnitude. Therefore, as we move from our home to the shop and then back to home, displacement is zero while distance is not zero.

## When acceleration is positive and negative?

When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration. In Example B, the object is moving in the negative direction (i.e., has a negative velocity) and is slowing down.

## Can distance be zero if no explain?

Displacement can be zero but distance cannot be zero because distance is the total path covered but displacement is the shortst distance between the initial and final position. It can be zero at the end of one round. if dist. 0 then there no displacement.

## What is negative acceleration called?

The other name of negative acceleration is Retardation or Deceleration. A deceleration is opposite to the acceleration. The deceleration means the decrease in the speed of body/object movement.
