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.

Avg velocity is the speed you are going. Constant acceleration is the rate you increase your speed. = =

Speed is how fast you are going. Velocity is how fast you are going and what direction you are headed in.

Direction. Velocity has speed and direction

If there is acceleration (uniform or otherwise, but non-zero acceleration), the velocity changes. Constant velocity means that the velocity does not change.

Velocity is an instantaneous measure. Mathematically, it is the limiting value of the change in the position vector divided by the change in time as the latter tends to zero. Over larger time periods, the average velocity is the total change in the position vector divided by the total change in time. If velocity is constant, the average velocity will be the same as the instantaneous velocity.

Speed is a scalar (Only has magnitude, no direction) Velocity is a vector (Has magnitude and direction)

the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object

No. You can't tell the difference, for one reason: There IS no difference.

Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.

average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)

Velocity is a measure of speed at any one instant and acceleration is a measure of change in speedAcceleration is defined as the rate at which velocity changes.Constant velocity doesn't change, so it's a condition of zero acceleration.

Average velocity is simply displacement over time. Instantaneous velocity is the velocity at any given instant, or the displacement over an infinitely small amount of time.

What is the difference between a satellite and a probe with regard to orbital velocity and escape velocity

Uniform velocity basically means that the velocity is constant. It means that the velocity of a give object never changes. Variable velocity means that a given object is either accelerating or decelerating.

Average speed is a representation of all your speeds between two points, constant speed is just unchanging speed.

my last physics class was about three years ago, but a dont think there is a difference. constant and uniform mean the same thing, it means it is not increasing or decreasing, therefore it is constant or uniform.

If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.

"Uniform motion" means constant velocity ... constant speed in a straight line. "Acceleration" means any change in velocity ... speed or direction. So 'uniform motion' means zero acceleration.

Acceleration is the difference between constant and non-constant motion.

Answer: No, the speed is constant, but the velocity changes, since the direction changes. Please be sure you understand the difference between "speed" and "velocity", as used in physics. Speed is scalar which has only magnitude but not direction Whereas velocity is having both. So is a vector quantitiy

speed is a scalar quantity ie it has no directions...........whereas velocity is a vector quantity ie it has directions...................Also speed has distance n velocity has displacement

constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.

Zero velocity means the object has no speed, that is, it's not moving. Zero acceleration means the object is moving with constant speed in a straight line, that is, its velocity is not changing.

Balanced forces are forces that are balanced. They must not be moving or must be moving with a constant velocity.
