Could be worn valve guides and/or seals
Certain types of tires may cause a brief humming noise after your initial acceleration. The transmission may also cause a brief humming noise.
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
No a force causes acceleration.
Force causes acceleration.
There is no force of acceleration. Acceleration is the rate at which velocity changes over time. A net force causes acceleration.
Every force causes acceleration, if it's not opposed and canceled by other forces.
There is no force of acceleration. Acceleration is the rate at which velocity changes over time. A net force causes acceleration.
That the force that causes the acceleration is not constant.
Neither. Force causes acceleration of mass. Mathematically, Force = Mass * Acceleration.
The force which causes acceleration towards the centre of a circle is called Centripetal force but what causes it can vary.
are you sure is a valve noise?? or is a piston slap?
