Yes; although speed ( a scalar quantity) may be constant the velocity ( a vector with quantity and direction) is changing because the direction is changing
Yes. While you go around the curve, your direction change, ergo, your velocity also changes.
Velocity is a vector quantity. So direction is important But speed is a scalar. Body moving around a circle may go with uniform speed but not with uniform velocity as direction is changing continuously
. . . velocity, because one of the components of velocityis the direction of the speed.
A change in the vector or direction that you are traveling is considered an acceleration; even if you don't change speed. This would be the case for going around in a merry-go-round, e.g. You are accelerating (changing direction), but the speed is constant (velocity is changing).
Of course. You need to go back and review the definitions of those terms. Acceleration is the rate at which velocity changes. If velocity is not changing, then there is no acceleration. But the velocity doesn't have to be zero just because it's not changing. Velocity is the speed of an object and the direction in which it's moving. If it's moving at a constant speed in a straight line, then it has plenty of velocity. But since the speed isn't changing and the direction isn't changing, there's no acceleration. If acceleration comes along somehow ... such as by igniting a rocket motor, or gravity pulling the object downward, or someone reaching out and giving the object a push, then the speed or direction may change, and that'll be a change of velocity.
Velocity is a vector, meaning that along with the measurement of speed in meters/second, it also needs a direction. If a car was driving North at 10ms-1 that would be its velocity at that point. The car then turns left so it's travelling west at 10ms-1. The car's velocity has changed, therefore there must have been some acceleration for the car's velocity to have changed. That acceleration is always towards the middle of the circle that it is turning
yes
You may go off the road.
A curve to the left, the vehicle would go to the right with no steering. A curve to the right, the vehicle would go left with no steering. Because any object in motion will continue to go straight unless another force takes it in another direction.
Centripetal force is always changing as it is a direct result as a change in velocity. This can be experienced when you drive in your car and go on an off or on ramp. You feel as though you are being pushed sideways.
Any object moving in a circle (as in a centrifuge, or a planet in an orbit) is accelerating. More generally, any object that moves in a curve is accelerating (such as a car moving in a curve on the road).
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
