Yes, if you are going in a circle or otherwise changing direction.
What else can I help you with?
Can the velocity of a body be constant still varying its speed?
Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.
Can a body have a constant velocity and still have varying speed?
Yes, if you are going in a circle or otherwise changing direction.
Can a body have constant speed and still have a varying velocity?
Yes, if you are going in a circle or otherwise changing direction.
Can a body have constant velocity and changing speed?
No, in order for the velocity to be constant, the speed has to be constant. Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour). Velocity is a vector, which indicates that it needs a measure of its displacement and a direction. (A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed. A car can not be slowing down yet still be going the same speed and direction.
Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
How could an object accelerate was still traveling at a constant speed?
An object can accelerate while still traveling at a constant speed if it changes direction. Acceleration is the rate of change of velocity, so even if the speed remains constant, a change in direction would still require acceleration.
Why does acceleration change when speed does not?
Acceleration is the rate of change of speed, so if speed is constant, acceleration is zero. However, if speed is constant but direction is changing (e.g. moving in a circle at constant speed), the velocity is changing, and thus there is still acceleration.
The velocity of an object can what if the speed of an object remains constant?
The velocity of an object can change if the object changes direction even though the speed remains constant. Velocity is a vector quantity that includes both speed and direction, so any change in direction will result in a change in velocity.
Why does a car traveling at constant speed can accelerate while a car at constant velocity connot?
The question is inherantly flawed. A car traveling at a constant speed cannot accelerate, if it could it's speed would not be constant. "Constant speed" means that speed is not increasing or decreasing but remain consistent over time. For example, if you cover 10 feet during each second, your speed is constant. "Constant velocity" implies constant speed, but it has an additional constraint: you can't change your direction. If you travel constantly at 10 feet per second in a straight line, then your speed is constant and your velocity is constant. But if you travel constantly at 10 feet per second in a wiggly line (or a circle, or anything not straight), then your speed is constant but your velocity is NOT constant. If you travel at a constant speed but change direction, velocity is changed. Or if you travel in the same direction but change the speed, velocity is changed. Average speed is is easier: distance/time So, your question should read: Why can a car traveling at an average speed accelerate, but a car traveling at constant speed cannot? Or Why am I asking the wrong questions?
Can a body have 0 velocity and still acceleration?
Yes, a body can have zero velocity and still have acceleration if its speed changes directions while its magnitude remains constant. This situation occurs when an object is moving in a circular path at a constant speed. The change in direction of velocity due to the circular motion results in centripetal acceleration.
If the velocity is constant does that mean that there is no change in momentum?
No, a constant velocity means that there is no change in speed but there can still be a change in direction, which would lead to a change in momentum since momentum is a vector quantity that considers both speed and direction.
Can an object be accelerated if it has a constant speed?
Yes. Acceleration means either speed or direction is changing. If direction is changing,then that's acceleration, even if speed is constant.
