What else can I help you with?
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.
What happens to an objects speed if it travels with zero acceleration?
If an object travels with zero acceleration, its speed remains constant. This means that the object maintains the same speed throughout its motion and does not change its velocity.
Is the velocity of an object in UCM constant?
No, the velocity of an object in uniform circular motion (UCM) is not constant. While the speed of the object remains constant, the velocity changes continuously in direction due to the centripetal acceleration required to keep the object moving in a circle.
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.
What happens to an object acceleration as it goes from free fall to terminal velocity?
As an object falls freely, its acceleration remains constant at approximately 9.8 m/s^2 until it reaches terminal velocity. Once it reaches terminal velocity, the acceleration becomes zero as the forces acting on the object balance out, resulting in a constant velocity.
What does mean the velocity remains constant?
When an object's velocity remains constant, it means the speed and direction of the object's motion do not change. This implies that the object is moving at a consistent rate without speeding up, slowing down, or changing course.
When no unbalanced forces act on an object the object can have no?
If forces on an object are balanced, the object will not accelerate - i.e., its velocity won't change.
What types of forces determine whether an object remains at rest or moves at a constant velocity?
The types of forces that determine whether an object remains at rest or moves at a constant velocity are balanced forces. If the forces acting on an object are equal in size and opposite in direction, the object will remain at rest. If the forces are balanced and in the same direction, the object will move at a constant velocity.
What is Motion without acceleration?
Motion without acceleration is when an object is moving at a constant speed in a straight line. In this scenario, the object's velocity remains constant and there is no change in its speed or direction.
Velocity can change if the speed and direction of the object changes and can change if the object remains blank fill in the blank?
If the object remains in uniform circular motion, its velocity can change even if the speed remains constant. This is because velocity is a vector quantity that includes both speed and direction, so any change in direction will result in a change in velocity.
What happens to the acceleration and velocity when an object in free fall moves downward?
In free fall, the acceleration of the object remains constant at 9.8 m/s^2 directed downward towards the center of the Earth. The object's velocity will increase as it falls due to the constant acceleration, until it reaches terminal velocity if air resistance is present.
