What is an object that always changes the velocity of the object?
A force is an object that can change the velocity of another object. This could be due to various factors such as gravity, friction, or an applied force from another object.
A change in a moving object's direction always results in a change in its?
velocity. When an object changes direction, its velocity vector changes, even if the object's speed remains constant. This change in velocity can be caused by forces such as gravity or friction acting on the object.
Why the speed of an object is constant while the velocity is not?
Speed is the magnitude of velocity, so if the speed of an object is constant, it means that the object is moving at a consistent rate. Velocity, on the other hand, is a vector quantity that includes both speed and direction, so if the direction of an object changes, its velocity changes even if the speed remains constant.
What happens when velocity changes?
When velocity changes, the speed and/or direction of an object's motion is altered. This can result in acceleration or deceleration, depending on the direction of the change in velocity. If the velocity increases, the object is accelerating; if the velocity decreases, the object is decelerating.
Is acceleration how quickly an object's velocity changes?
Acceleration is the rate at which an object's velocity changes over time. It can involve an increase or decrease in speed, or a change in direction.
