What does the graph of acceleration vs. time look for something going constant velocity?
a horizontal line
What does the graph of acceleration vs. time look for something going a constant velocity?
a horizontal line
Is the velocity constant if a car is going around a curve?
No, the velocity of a car is not constant when it is going around a curve. The direction of the car's velocity is changing as it navigates the curve, even if its speed remains the same, so the velocity is not constant.
Which describe the average velocity f a bicycle going constant speed in a constant direction?
The average velocity of a bicycle going at a constant speed in a constant direction is equal to the speed of the bicycle. It is a vector quantity that indicates the displacement covered by the bicycle in a given time period, taking into account both the distance and the direction.
The graph of acceleration vs time for something going a constant positive velocity has what kind of characteristics?
The graph of acceleration vs time for something going at a constant positive velocity would be a horizontal line at zero on the acceleration axis. This is because there is no change in velocity, so the acceleration is constant and equal to zero.
What does the graph of accelaration vs.time look like for something going a constant velocity?
Constant velocity implies zero acceleration, so you would have a horizontal line, identical to the x-axis.
What of the he graph of acceleration vs time for something going a constant positive velocity has characteristic?
The acceleration vs. time graph for something moving at a constant positive velocity will be a horizontal line at zero acceleration. This is because acceleration is the rate of change of velocity, and if the velocity is not changing (constant), then the acceleration is zero.
Which describes the average velocity of a bicycle going at a constant speed in constant direction?
The total displacement divided by the time. The slope of the displacement vs. time graph.
Is speed and velocity the same thing?
Scientifically, Both are are distance over time. Speed is a scalar, however, which means there is no direction involved. Velocity on the other hand is known as vector, meaning direction is included. So like when an object is spinning round and around, its speed can be constant, but, because the direction is changing, the velocity does not remain constant. In common speech though the two are interchangeable
Is constant speed current velocity?
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
Can a velocity of a body change its speed is constant?
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
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.
