The velocity of an object can change even if the speed remains constant?
Yes. The velocity can change if the speed remains constant and the direction changes.
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.
If an object moves with constant acceleration what happens to the velocity?
The velocity increases at a constant rate.
Can the speed of an object changes if there is constant velocity?
No, constant velocity implies constant speed. But velocity can change even when speed remains constant, since speed is a scalar quantity but velocity is a vector quantity.
If an object is moving at constant velocity what happens to the net force?
If the object is moving at constant velocity, that's an indication that the net force on it is zero.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.
When air resistance balances the weight of an object that is falling the velocity remains blank?
Constant
What happens to the velocity of an object when balanced forces act on it?
The velocity is constant and there is no net or unbalanced force.
For an object to be moving at a constant velocity is it necessary for it to be moving in a straight line?
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
What happens to the displacement velocity and acceleration of an object as it falls through the air to the ground?
Displacement: Grows with time, at an increaing rate. Velocity: Grows with time, at a constant rate. Acceleration: Greater than zero, remains constant with time.
Which quantity remains constant when the net force on an object is increase?
When net force on an unconstrained object changes, the object's acceleration, velocity, position, and possibly speed and shape all change. Its mass remains constant.
The velocity of an object can what if the speed of an object remains constant?
The velocity can still change, even if the speed doesn't. This is because velocity is a vector - not only the magnitude is important, but also the direction.
