Is it possible to experience centripetal acceleration but not tangential acceleration?
Yes, it is possible to experience centripetal acceleration without tangential acceleration. Centripetal acceleration is the acceleration directed towards the center of a circular path, while tangential acceleration is the acceleration along the direction of motion. In cases where an object is moving in a circular path at a constant speed, there is centripetal acceleration but no tangential acceleration.
What else can I help you with?
Is it possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration?
Yes, it is possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration. This occurs when an object is moving in the positive direction but slowing down due to a decrease in its speed.
A car is moving with constant speed and yet the acceleration and net force are not equal to zero how is this possible?
This scenario is possible if the car is moving in a circular path at constant speed. In circular motion, even though the speed is constant, the direction of the velocity is constantly changing, which requires a centripetal acceleration towards the center of the circle. This acceleration is provided by a net force, known as the centripetal force, acting towards the center of the circular path.
Is it possible for a body to move in a circle with constant speed constant linear velocity?
While your speed may be the same, your direction is constantly changing. So there is an angular acceleration. The force caused by this is called centripetal force, and it points towards the center of the circle. You can know this by feeling it, or by drawing a picture of the force system. Acceleration is broken up into normal and tangential components for rotation. The tangential is zero because you are moving at a constant speed, however the normal is not zero, and points to the center of the circle by definition.
Is it possible for an object in freefall to have no acceleration?
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
Can a situation exist in which an object has zero velocity and nonzero acceleration?
Yes, it is possible for an object to have zero velocity and non-zero acceleration if the object is changing direction without changing speed. This can happen when an object is in circular motion, where its velocity is always tangential to the circle but its acceleration points towards the center.
Is it possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration?
Yes, it is possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration. This occurs when an object is moving in the positive direction but slowing down due to a decrease in its speed.

Is it possible to achieve a constant acceleration?
Yes - for a while. Or indefinitely, if you will accept zero acceleration as "constant acceleration".
Is it possible for a body to have the same acceleration and velocity?
The velocity and acceleration can have the same numeric value, but the units will be different. ----------------------------------------------------------------------------------------- No it is not possible. Because so long there is acceleration then the velocity has to change either in magnitude or in direction or in both. So it is not at all possible for acceleration and velocity to be the same simultaneously.
Can a situation exist in which an object has zero velocity and nonzero acceleration?
Yes, it is possible for an object to have zero velocity and non-zero acceleration if the object is changing direction without changing speed. This can happen when an object is in circular motion, where its velocity is always tangential to the circle but its acceleration points towards the center.
How is the acceleration of falling bodies determine experimentally?
For example, you can time how long it takes for an object to reach the floor. You also need to measure how far it falls down. If you assume constant acceleration, there is only one possible acceleration for any possible set of measurements.
Is it possible for a body to have an acceleration when moving with constant speed explain?
Yes, it's acceleration will be zero because the velocity isn't changing, but it has an acceleration. Think of it in terms of integration and derivation. Acceleration is the derivative of velocity, so if velocity is a constant number the acceleration must be zero.Generally if value of acceleration is "zero", we consider it to mean that there is NO acceleration. The question that was actually answered above was "Can acceleration be DEFINED fora body moving at constant speed?"It is possible for an object to be moving at a constant angular speed and yet have an effective acceleration in a tangential direction.===========================================Both of you guys are missing the most important point here, with the resultthat you have to twist your own arm almost to the point of dislocation in orderto state an answer.The essential underlying consideration is that, contrary to popular misconception,"acceleration" does not mean 'speeding up', or even 'changing speed'. It means"change in velocity", and "velocity" means "speed anddirection". If either speedor direction change, then that means there is 'acceleration'.The answer to the question is simple, and almost entirely non-technical. It is:"Yes, because 'acceleration' means change of either speed or direction. So, ifthe direction of the body's motion is changing, then the body has acceleration,even if its speed is constant."
Is it possible for a body to have acceleration when moving with constant veloctiy?
No, because acceleration is the rate of change of velocity.
Is it possible to differentiate acceleration with respect to time?
The variable obtained by dividing the acceleration by time is called "jerk".
Is it possible that a body be in accelarated motion under a force acting on a body yet no work is being done by the force?
Yes, that is possible. For example, an object in circular motion, accelerated towards the center. The force (and the acceleration) is normal (perpendicular) to the movement; thus, the dot product between the force and the displacement is zero.
