When it "huff and puffs" that's usually when its building up the acceleration to go faster
Drive shaft is going out
Slow engine RPM is the main reason a car may be sluggish while accelerating. However, it also could be due to the oil.
dirty fuel line
To calculate how far the car travels while accelerating, you would need to use the kinematic equation: distance = (initial velocity × time) + (0.5 × acceleration × time^2). Plug in the values of the initial velocity, final velocity, and acceleration into the formula to find the distance traveled.
A gas leak with the car sputtering while accelerating could be a hole in the vacuum hose that controls the flow of gasoline out of the tank. This type of leak is usually not caused by the fuel pump itself.
bad wheel bearings
noise and jolting is present whilst car is idolling and accelerating
Frame of reference is the measurement or observation that tells you that a car is accelerating. It uses the second law of motion to tell you rather or not the car is accelerating.
A car can be slowing down while still accelerating if its speed is decreasing but the direction of its velocity is changing. For example, if a car is moving in a curve, its speed may be decreasing but it is still accelerating towards the center of the turn. This is known as centripetal acceleration.
sounds like a cv joint
My car is accelerating at 10 miles per hour per hour.
your car might be weak on accelerating because it isn't firing on all cylinders.
