What are the similarities between uniform and nonuniform motion?
in uniform motion velocity not changes with time but in non uniform motion velocity changes with time.
Which describes how velocity changes with time?
average speed.
What is a nonuniform motion?
when the direction or the speed of motion changes then it is called non-uniform motion
It is possible for a body to have acceleration when moving with constant speed and velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
How acceleration is different from velocity?
Velocity is the rate at which location changes, and the direction in which location changes. Acceleration is the rate at which the size of velocity changes, and the direction in which velocity changes.
An object in circular motion is constantly acceleratingtrue or false?
True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True.

What happens when you have unbalanced forces acting on an object?
Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.
What are acceleration and velocity?
'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.
Calculate average velocity and average speed?
sharon sprinter changes her speed from 4.5m/s to 7.5m/s in the middle 1.5 seconds of a 100m race. what is her average velocity for this time period?
What changes a body's velocity?
A force changes a body's velocity.
How does the change in angle changes the velocity?
Velocity is speed in a direction or speed at an angle. The velocity changes when the speed or angle changes.
How velocity different from speed?
Velocity is acceleration and direction put together. The velocity of something changes if either acceleration or direction changes. Speed is just the average MPH measure. Velocity is not acceleration and direction put together. In that kind of description, velocity is is speed and direction put together. Velocity is a vector, whose size is the speed.
Th rate at which velocity changes?
Velocity changes are referred to as acceleration.
What causes a change in velocity?
Velocity changes when an objects position changes.
What is impulse momentum theory?
Impulse momentum theory: when force is applied to a rigid body it changes the momentum of the body. it is calculated with respect to time and also the velocity is calculated.
Does velocity changes when the direction of motion changes?
Yes. The velocity changes when the direction of motion changes, because the definition of 'velocity' is 'speed and the direction'. If either speed or direction changes, then we say the velocity has changed. Notice that if the direction changes, then the velocity changes even if the speed doesn't. "Velocity" is not just a bigger word that you use for 'speed' when you want to sound smart. They mean different things.
In what two ways can velocity be changed?
Velocity changes when the direction of the motion changes.
How does velocity change your momentum?
Momentum is defined as the product of (mass) times (velocity). If the velocity changes, then that product changes.
What happens to an object's velocity when it accelerates?
"Acceleration" implies that the velocity changes.
What is the difference between constant velocity and average velocity?
The average velocity is trying to find how fast the car is going at an average rate. However, constant velocity means that the car is going at an unchanged velocity. Say a car is going at 75 m/s and then changes to 50 m/s and then changes to 25 m/s in 30 minutes. The car is going at different velocities at different times. To find the average, you simply just add the 3 together, then divide by 3 giving you, 50 m/s In the 30 minutes, it's average velocity was 50 m/s However, for a car going at a constant velocity, it means that the velocity never changes. Say a car is going at a constant velocity for 30 minutes at 50 m/s. In those 30 minutes, the car will never change it's velocity and remain at 50 m/s. Constant means that it doesn't change.
What are the similarities and differences between speed velocity and acceleration?
Velocity is speed with a direction. Acceleration is the rate at which velocity changes, just as velocity is the rate at which position changes (and jerk is the rate at which acceleration changes).
What happens to an objects velocity as it accelerates?
The velocity changes. Acceleration refers to the rate of change of velocity, i.e., how fast it changes.
What does average of kinetic energy mean?
kinetci energy,k.e.=1/2(mv2) where m=mass v=velocity average k.e. means we need to take into account the average velocity because mass never changes
What is the rate at what velocity changes with time?
The rate at which velocity changes in time is called acceleration.
What can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
