Is it possible for a body moving with a uniform speed to have acceleration?

Yes. This is exactly the case when an object is thrown on the surface of the Earth. Consider an (American) football thrown in the air. This ball has the force of gravity accelerating it downward, but there is no force acting on it horizontally, thus there is no acceleration horizontally. As a result, since acceleration is the rate of change in velocity, the velocity in the vertical direction is changing, whereas the velocity in the horizontal direction is not.

In this case, the horizontal component doesn't change (there is no force that pulls the object sideways), but the vertical component does change (since gravity pulls the object downwards).

∙ 13y agoAcceleration is defined as The rate of change of Velocity.
Which means that for acceleration there must be Variable Velocity/ Speed. and not uniform

Why the velocity and acceleration of body moving with uniform speed in circular path will be mutually perpendicular?
as direction is changing
Can it be possible that a particle have constant speed must have zero acceleration?
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".
Can a particle moving with uniform speed along a curved path have acceleration?
Yes, due to its change in direction of motion.
Is it possible when a body to have acceleration when moving constant speed?
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)

How is it possible for a car moving at constant speed be accelerating?
Not possible, acceleration dV/dt =0.
Can a particle moving with uniform speed along a curved path have acceleration?
Yes, due to its change in direction of motion.
Under what circumstances can an object moving with an constant speed (uniform magnitude oits velocity) have an acceleration?
When the direction changes. A simple case is an object moving in a circle, at constant speed.

Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
A can rolled down an incline and accelerated at a uniform rate It started from rest a speed of 0 ms and reached the bottom of the incline moving with a speed of 1.8ms state the average speed?
For uniform acceleration the average speed is the initial speed plus the final speed divided by two.
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
How are velocity and acceleration different?
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
