What is the formula for maximum speed?
The formula for speed is simply v(0)t. 19.8*15.9= 314.82 m/s for the maximum speed.
What was my average speed?
The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed, add the two together, and divide by 2.
What is retardation formula?
The formula for retardation is- r=−a⇒r=−(v−u)t. Here, r is the retardation. a is the acceleration. v is the final velocity.
What is retardation example?
When the velocity of a body decreases, its acceleration is negative. Negative acceleration is called ‘retardation’ or ‘deceleration’. For example, when a stone is thrown upwards, it is under retardation. Similarly, when a bus approaches a bus-stop, its motion gets retarded.
Is retardation a force?
Forces that resist relative motion (like air resistance or friction) are called ‘retarding forces’. Sometimes they are also just called ‘resisting forces’, though. Whether the forces actually ‘resist motion’ depends on who’s looking at a particular situation.
What is the symbol of retardation?
Answer:There is no symbol for retardation. It is written as ‘retardation’ only.
Is retardation and acceleration same?
Acceleration is the increase in velocity per second, while retardation is the decrease in velocity per second. Thus, retardation is negative acceleration. In general, acceleration is taken positive, while retardation is taken negative.
Is retardation positive or negative?
If the velocity of the object decreases then the object is said to have a negative acceleration and the meaning of retardation is decreased. Therefore, retardation means negative acceleration.
How do you find retardation?
Retardation is negative acceleration. By definition of acceleration, we know v = u + at. Therefore we can find retardation. Also, we can find the distance covered by the car from the formula s=ut+12at2.
