Can an object move faster than its average speed?
Yes, an average speed is only the difference between the highest and lowest speeds over a specified length of time. If an object accelerates from a standing start, accelerates to 10 metres per second over ten seconds and then slows to a stop at the same rate, the average speed would be 5 m/s. It is more difficult to calculate an accurate average speed when travelling at varying speeds.
Will the acceleration be zero if velocity is constant in velocity time graph?
Yes, by definition, Acceleration is the derivative of velocity. From Calculus, we know, the derivative of any constant function is simply 0. Therefore, any velocity time graph containing a constant velocity function will have an acceleration function = 0. c'=0 or c d/dx=0 also, there is a very simple, and nice progression to things in the field of Kinematics. where given a function, whether it be position, velocity, or acceleration, you can find the other through calculus. the progression for integration goes as follows, jolt (the feeling you get when acceleration changes), acceleration, velocity, position. And the reverse for derivatives. Having a velocity function of something like 55mph, think of it as driving on the freeway, absent of outside forces of friction, air resistance and hills, you never have to accelerate (positively, or negatively) to maintain speed, and the math backs that up. 55 is constant, and the derivative is 0. now if you had a velocity function such as 2x^2 + 5, also known as a parabolic function, you would take the derivative and get an acceleration of 4x, and a jolt of 4, and if you integrate to get position, you would have 2/3x^3+5x. Its all about the math.
How do you use standstill in a sentence?
The auto accident caused traffic to come to a standstill on the freeway.
All of these actions describe a change in velocity except?
the bus drove east on the freeway for 5 minutes
What units are used to express velocity?
In physics, velocity is most commonly measured in meters per second (m/s). However, you can measure velocity in other units as well.Here are a few more: feet per second (ft/s), miles per hour (mph).Please note that velocity is a vector quantity, which means not only do you need a speed but you also need a direction. Many people interchange speed and velocity in common language. Yet most don't understand the difference between the two.For example, if you say I was going 70 miles per hour on the freeway, you are describing your speed. But if you say I was going 70 mph on the north bound freeway, that is a velocity because it has a direction.the unit of velocity is m/s

What is the power button on the shifter for?
The power button is a form of overdrive. It drops the transmission one gear down. Handy for passing or entering the freeway when you need a little more power and acceleration.

When entering a freeway what should you do?
Increase speed to merge with the flow of traffic.
