## What happens if a ball is moving at a constant velocity?

As the ball is moving with a constant velocity, therefore there is no acceleration. Thus, balanced forces are acting on the ball.

## How do I know if something is moving at a constant velocity?

An object has constant velocity when both the magnitude and direction of the rate at which such an object is changing its position remain constant. In other words, for an object to have constant velocity its movement has to not change directions over time and the object must have constant speed as well.

## What is an object that is moving at a constant velocity?

Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time.

## Does a ball rolling on a smooth horizontal plane has almost different velocity?

A ball rolling on a smooth horizontal plane has almost constant velocity.

## Does a projectile move with constant velocity?

Projectile motion, then, is a combination of vertical motion with constant acceleration (free fall that we have already discussed) and horizontal motion with constant velocity (which we also understand).

## Can constant velocity be zero?

Derivative of velocity with respect to time is acceleration. That means if accelerations is zero, velocity must be constant. Now that constant could be anything like it could be 5 m/s . Also if the velocity is 0(which is itself a constant) also indicates that acceleration is zero.

## In which case velocity is zero?

Yes, it is possible when an object is thrown upward then at the highest point its velocity is zero and it has acceleration due to gravity, which is finite.

## What is an example of constant velocity?

Answer to Essential Question 2.3: Some examples of constant velocity (or at least almost- constant velocity) motion include (among many others): • A car traveling at constant speed without changing direction. A hockey puck sliding across ice.

## What is the SI unit of momentum?

Momentum | |
---|---|

SI unit | kilogram meter per second (kg⋅m/s) |

Common symbols | p, p |

Other units | slug⋅ft/s |

Dimension | MLT^{−}^{1} |

## What is the formula for constant velocity?

The equation for constant velocity is v = d/t, where v is velocity, d is the distance traveled, and t is time. This equation assumes that the object moves at a constant velocity with no acceleration or deceleration.

## Why is work zero at constant velocity?

If a body is moving with a constant velocity, the net force on it is zero. So the net work done on it will be zero. Q. The work done on a block moving with constant velocity is zero.

## Can a ball have a constant speed but varying velocity?

Yes, if the body is traveling at a uniform speed on a circular track, its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.

## Why does horizontal velocity change?

There is only one force acting on the object in the air, that is due to gravity, acting downwards. Since no force is acting in a horizontal direction therefore the magnitude of velocity and angle is remaining constant.

## What is the velocity of a ball thrown horizontally?

The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
