The speed.
The speed.
Yes, momentum changes when speed changes because momentum is directly proportional to an object's velocity. When an object's speed changes, its momentum will also change accordingly.
If an object's speed changes, it means that it is either speeding up or slowing down. If an object's direction changes, its velocity changes as well, as velocity is a vector quantity that includes both speed and direction. These changes in speed and direction are typically caused by forces acting on the object.
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
Yes, when an object changes speed, its acceleration changes. Acceleration is a measure of how quickly the speed of an object changes over time. So, if the speed changes, the acceleration of the object will also change.
If someone's speed changes, it means they are moving faster or slower than before. If someone's direction changes, it means they are now moving in a different path or route. Both changes can affect the individual's position, velocity, and acceleration.
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
The angle of the graphed slope changes with changes in speed.
The rate at which speed changes, and the direction in which it changes.
Acceleration is the rate that speed changes.
when speed increases, velocity changes.
Acceleration is a measure of how quickly the speed of an object changes over time, not the speed itself. Speed refers to the rate at which an object covers distance, while acceleration refers to how the speed of the object changes. So, acceleration is not a kind of speed, but rather a measure of how speed changes.
