What else can I help you with?
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
Is the velocity constant if a car is going around a curve?
No, the velocity of a car is not constant when it is going around a curve. The direction of the car's velocity is changing as it navigates the curve, even if its speed remains the same, so the velocity is not constant.
What kind of speed has no acceleration?
A constant speed has no acceleration. When an object is moving at a constant speed, its velocity remains the same over time, and there is no change in acceleration.
When the velocity of the body is doubled its acceleration?
When the velocity of a body is doubled, its acceleration remains the same if the direction of motion remains constant. Velocity is the rate of change of position of an object over time, while acceleration is the rate of change of velocity over time. If the velocity is doubled while the direction remains constant, the acceleration does not change.
What happens to the velocity of an object even if the speed of an object remains constant?
Velocity can change even if speed is constant.

When the velocity of the body is doubled its acceleration?
When the velocity of a body is doubled, its acceleration remains the same if the direction of motion remains constant. Velocity is the rate of change of position of an object over time, while acceleration is the rate of change of velocity over time. If the velocity is doubled while the direction remains constant, the acceleration does not change.
Why the horizontal velocity component remains constant and the vertical velocity component continuously changes during projectile motion?
The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming no air resistance), so the velocity remains unchanged. The vertical velocity component changes due to the force of gravity, which accelerates the projectile downward, increasing its velocity as it falls.
If the speed of an does NOT change the object is traveling at a what?
It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
The velocity of the body is constant if it covers equal displacements in equal intervals of time. This is because velocity is defined as the rate of change of displacement with respect to time. If the body is covering equal distances at equal intervals, then the velocity remains constant.
With which constant velocity the disk rotates at a constant speed?
The disk rotates at a constant speed when the angular velocity remains constant. This means the disk rotates at a constant angular velocity, maintaining a consistent rate of rotation without speeding up or slowing down.
How does mass affect velocity?
When mass increases, velocity remains constant if the force applied remains constant. However, if the applied force stays the same, an increase in mass will require more force to achieve the same acceleration, which may lead to a decrease in velocity.
Can you have constant speed but change in velocity?
Yes, you can have constant speed but change in velocity if the direction of motion changes. Velocity is a vector quantity that includes both speed and direction. So, even if the speed remains constant, if the direction changes, the velocity changes.
