If a car is traveling at a constant speed but is going around a curve what can you say about the cars motion?
The car is accelerating because its direction is changing due to the curve. Although the speed may be constant, the car is undergoing centripetal acceleration toward the center of the curve to maintain its path.
What is the symbol for speed and velocity?
The symbol for speed is "v" and the symbol for velocity is "v" with an arrow on top to indicate its direction.
Can a change in velocity always indicate a change in speed?
No, a change in velocity does not always indicate a change in speed. Velocity is a vector quantity that includes both speed and direction. A change in velocity could result from a change in speed, direction, or both.
What is the rate of decrease in velocity?
The rate of decrease in velocity is known as deceleration. It represents how quickly an object's velocity is decreasing over time. This can be calculated using the formula for acceleration, but with a negative sign to indicate a decrease in velocity.
Does velocity indicates how long it takes to get from one place to another?
Velocity indicates the speed and direction of an object's movement but does not directly indicate how long it will take to travel from one place to another. Time taken for travel depends on distance, velocity, and any changes in speed or direction.
Why is velocity and speed same unit?
Velocity is speed, plus an indication of direction. To indicate a velocity, you can indicate a speed (this will logically use units of speed), and a direction.

What does the slope of a distanced-time graph indicate?
magnitude of velocity
What is the symbol for speed and velocity?
The symbol for speed is "v" and the symbol for velocity is "v" with an arrow on top to indicate its direction.
What does a flat line on a velocity -time graph represent?
A flat line would indicate a constant velocity, no change in speed.
Can a change in velocity always indicate a change in speed?
No, a change in velocity does not always indicate a change in speed. Velocity is a vector quantity that includes both speed and direction. A change in velocity could result from a change in speed, direction, or both.
What is the rate of decrease in velocity?
The rate of decrease in velocity is known as deceleration. It represents how quickly an object's velocity is decreasing over time. This can be calculated using the formula for acceleration, but with a negative sign to indicate a decrease in velocity.
Does the horizontal line on the velocity vs time graph indicate a constant and positive acceleration?
No, a horizontal line on a velocity vs. time graph indicates a constant velocity, not acceleration. An acceleration would be represented by a non-zero slope on a velocity vs. time graph.
Why velocity diagram are required for centrifugal pumps?
velocity diagram indicate the effect of vane angle, effect of jet angle on impeller speed
Does velocity indicates how long it takes to get from one place to another?
Velocity indicates the speed and direction of an object's movement but does not directly indicate how long it will take to travel from one place to another. Time taken for travel depends on distance, velocity, and any changes in speed or direction.
What is a synonym for velocity?
There is no synonym to velocity. there is no directionality in velocity. speed is a measure of rotation around a center expressed in revolutions per unit of time. Velocity is a measure of distance in units of time with no direction. Vectors indicate direction.
What does the slope of a distance vs time graph indicate about an object's motion?
instantaneous velocity
