## Can distance Travelled be zero?

Answer: No, Distance travelled cannot be zero when displacement is not zero because distance is always greater or equal to displacement……

## What happens to the velocity if acceleration is zero?

That means if accelerations is zero, velocity must be constant. … Also if the velocity is 0(which is itself a constant) also indicates that acceleration is zero.

## How do you know if acceleration is 0?

When acceleration is zero (that is, a = dv/dt = 0), rate of change of velocity is zero. That is, acceleration is zero when the velocity of the object is constant. Motion graphs represent the variations in distance, velocity and acceleration with time.

## What is acceleration at maximum speed?

Acceleration is the rate of change of velocity, or how quickly an athlete can increase the velocity of the motion. Maximum speed is the highest rate of speed an athlete can attain. … In terms of running, anytime the body starts, speeds up, or changes direction, it is accelerating.

## What is an example of negative acceleration?

Because the velocity/speed of this object is decreasing over time, this means there is a negative acceleration. A jet airliner starts at rest and moves down the runway in a straight line. After accelerating for 20 seconds, it reaches a speed of 80 meters per second.

## Can you have negative acceleration?

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

## What does 0 velocity mean?

Zero velocity is essentially no movement. What this means is that your change in position from time a to time b is zero. This happens when you throw an object to the sky. Just before it falls, when there is no force moving it upwards, it will remain motionless and its velocity will be zero.

## Does constant acceleration mean zero velocity?

Car 1 – Velocity and acceleration graphs Constant velocity means the acceleration is zero. The change in velocity over a certain time interval equals the area under the acceleration graph over that interval. In this case the velocity does not change, so there can be no area under the acceleration graph.

## When velocity is minimum What is acceleration?

So, when velocity is maximum, acceleration is minimum (zero).

## Can the Force be negative?

Yes, force can be negative. It means that the force is going to the opposite direction. … A ‘negative’ force is one that is acting in the direction opposite to what you decide to be the positive direction (Usually, upward is +ve, downward is -ve).

## Can speed be negative or zero?

The ratio of distance travelled and the time taken by a body can be zero but not negative. Since distance and time are positive quantities and speed is obtained by the ratio of these two quantities, speed cannot be negative.

## What happens when velocity is zero?

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. … Velocity is a vector quantity. As such, velocity is direction aware.

## Can an object be accelerating when its speed is zero?

b) Can an object be accelerating when its speed is zero? … Yes, acceleration is a change in velocity, so an object might be momentarily at rest but a split-second later have some speed, i.e. it can be changing its velocity even if it is momentarily at rest.

## Is it possible to have a negative velocity but a positive acceleration?

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).

## 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. However, an average velocity can be zero.

## Can distance Travelled by a moving body is zero?

Average speed for a moving body will never be zero. As DISTANCE is the path travelled by an object, so DISTANCE cannot be zero. HENCE average speed will never be zero. NOTE: If object returns to starting point, then displacement will be zero not DISTANCE.

## When acceleration is zero What is the maximum velocity?

According to me,when: magnitude of Force due to gravity> magnitude of Restoring force, then the velocity of the body increases. magnitude of Force due to gravity=magnitude of Restoring force, then the acceleration of the body is zero, and the body has maximum constant velocity.

## Can you have a zero acceleration but non zero velocity?

Answer and Explanation: Acceleration is the rate of change of velocity with time. As the velocity is a constant value over all the values of time, the rate of change of velocity is thus zero. So, acceleration is zero. So, zero acceleration and non zero velocity are possible for particles moving with constant velocity.

## Is the velocity ever zero?

Answer and Explanation: The velocity is never zero in the case of a projectile launched at a nonzero non-vertical angle with respect to the…

## Why is acceleration negative when velocity is positive?

Assuming rightward is positive, the velocity is positive whenever the car is moving to the right, and the velocity is negative whenever the car is moving to the left. The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.
