Why is the acceleration not constant even though the engine produces a constant force?

The acceleration was not constant because the force was not constant. P.S. In cases where acceleration is constant at some non-zero value, velocity will be changing.

Is acceleration constant when force is constant?

Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In this case, the constant acceleration due to gravity is written as g, and Newton’s Second Law becomes F = mg.

Can a car have a constant acceleration and a constant speed?

An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. If an object’s velocity is constant, however, its acceleration will be zero. Since it travels in a straight line, its direction does not change.

What is the acceleration for an object with constant force?

Originally Answered: Constant applied force means constant velocity, thus 0 acceleration, thus 0 net force according to the f=ma formula.

Can acceleration be constant when speed is not zero?

Yes it is possible for speed to be constant while the acceleration is not zero. Speed is the magnitude of the velocity vector. Unlike the velocity, which is vector quantity, the speed is a scalar quantity. As such, the speed only has magnitude.

What is the acceleration if it is a constant speed?

Acceleration is a kinematic quantity. Irrespective of what forces are acting, if the velocity is constant, the acceleration is zero.

What happens if acceleration is constant?

If acceleration is constant, then the velocity will change by a constant amount every second, in other words: velocity is NOT constant.

Why do we assume acceleration is constant?

We now make the important assumption that acceleration is constant. This assumption allows us to avoid using calculus to find instantaneous acceleration. Since acceleration is constant, the average and instantaneous accelerations are equal—that is, a – = a = constant .

What is non constant acceleration?

Non-uniform acceleration constitutes the most general description of motion. It refers to variation in the rate of change in velocity. Simply put, it means that acceleration changes during motion.

Why is acceleration non-zero when net force is constant?

Whenever there is a change in velocity, either due to a change in speed or a change in direction, there will be non-zero acceleration. Acceleration is not constant if the net force is not constant. Imagine a rocket propelled car.

Why was the acceleration not constant in this experiment?

The acceleration was not constant because the force was not constant. P.S. In cases where acceleration is constant at some non-zero value, velocity will be changing.

Can We have acceleration with a constant force acting on it?

Yes, we can have an acceleration even though a constant force acting on a system. As we know in classical mechanics mass m of an object is a constant, then if we apply a constant force F on the system it can create a constant acceleration a on it. A constant force of Gravity (F) produces a constant acceleration g on a definite amount of water.

Why is acceleration not constant at 3G?

Acceleration is not constant if the net force is not constant. Imagine a rocket propelled car. It has 3 rockets on the back. All the rockets ignite and forward acceleration is constant at 3g’s. Then one of the engines has a malfunction and quits.
