How do you calculate distance and revolutions?
You must buy a bicycle computer and attach it to your bike. They can calculate various things- speed, distance, RPM, time, tempertature, altitude, speed increase or decrease
How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
What is the difference between direct proportion and indirect proportion?
Two variables are said to be in direct proportion if, when you increase one by some multiple, the other also increases by that same multiple. Alternatively, both decrease by the same proportion. Two variables are in indirect (or inverse) proportion if an increase in one of them is associated with a decrease in the other, and conversely. The proportional change in both is the same. For example, if I change the speed at which I am driving, then the distance that I can cover in a fixed amount of time will change in the same proportion. Double my speed then double the distance, quadruple speed and quadruple distance, halve the speed and halve the distance. So speed and distance are directly proportional. Now think of speed and the time taken to do a fixed distance. Double my speed and halve the time. Halve the speed then double the time. So time taken is inversely proportional to speed.
Why is retardation called negative acceleration?
retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative acceleration.
How would decreasing the time it takes you to run a certain distance of your speed?
Decreasing the time, for the same distance, means you increase your speed. Remember that speed is distance / time.
Does your stopping distance increase or decrease with speed?
Stopping distance generally increases with speed. This is because as your speed increases, it takes longer to react to a hazard and the vehicle covers a greater distance while stopping. Additionally, higher speeds require more braking force to bring the vehicle to a complete stop.
When the speed of a vehicle doubles the braking distance is increased by approximately?
When the speed of a vehicle doubles, the braking distance is increased by approximately four times. This is because the braking distance is directly proportional to the square of the speed.
As speed increase the elements of your stopping distance and therefore your stopping distances as a whole?
Yes, as speed increases, both the reaction distance (distance traveled while identifying a hazard and initiating braking) and braking distance increase, leading to a longer total stopping distance. This is due to the greater momentum and energy that needs to be dissipated to come to a stop at higher speeds.
When speed is doubled the braking distance is doubled also?
This statement is not accurate. In reality, when speed is doubled, the braking distance is quadrupled, not doubled, assuming all other factors remain constant. This is because the braking distance is directly proportional to the square of the initial speed.
How does speed traction and gravity affect braking distance?
Speed: As speed increases, braking distance increases because the vehicle has more kinetic energy that needs to be dissipated in order to come to a stop. Traction: Higher traction allows the tires to grip the road better, reducing braking distance. Lower traction conditions, such as wet or icy roads, can increase braking distance due to reduced grip. Gravity: Gravity affects braking distance by influencing the weight and load distribution of the vehicle. Heavier vehicles may have longer braking distances as it takes more force to slow them down compared to lighter vehicles.
How changes in energy will affect tranportation and stopping distances?
An increase in energy will generally result in an increase in speed, which will in turn increase the stopping distance required for a vehicle to come to a complete stop. This is because the kinetic energy of a moving vehicle is directly linked to its speed, so the greater the energy, the greater the speed, and consequently the greater the stopping distance needed. Conversely, a decrease in energy will result in a decrease in speed and stopping distance.
Does Speed Affect Braking Distance Of A Vehicle?
Yes
What happens to to the speed of a motor if i increase or decrease the number of bulbs in a circit?
If you increase the number of bulbs in a circuit, the resistance in the circuit will increase, causing the motor's speed to decrease. If you decrease the number of bulbs, the resistance in the circuit will decrease, causing the motor's speed to increase.

How does mass speed of vehicle affect the braking distance?
t bvv
Why is the braking distance longer when the car is travelling at a higher speed?
Inertia.
Is distance directly or inversely proportional to time?
Distance is directly proportional to time when speed is constant, meaning that the farther you travel, the longer it takes. Conversely, distance is inversely proportional to time when speed varies, such that if you increase speed, you decrease the time it takes to travel a certain distance.
