Moving in the positive direction at an increasing speed. (Accelerating positively)
Any falling object has acceleration and velocity vectors in the same direction.
This is a moving object that is slowing down.
The net force is in the same direction as the acceleration of an object.
Yes. Acceleration is a change in velocity. As velocity is a vector (direction and speed) changing either the speed or direction will change the velocity and thus be an acceleration (or decelleration)
It is a vector. A scalar has only magnitude. A vector has magnitude and direction.Acceleration is a vector because it has magnitude and direction. That's why an object can be said to be accelerating if it has a circular rotation and a constant speed; even though it's speed isn't changing, it's direction constantly is. Displacement (s), velocity (v), and acceleration (a), are vectors because they have both magntude and direction.
. Velocity Acceleration
The answer is velocity.
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
Acceleration is the rate of change in velocity. (Velocity is speed+direction, it is a vector as well as acceleration). F=ma, where a is in ms^(-2).
A vector quantity measures the movement of a particular object in a given direction. An example of a vector quantity is velocity.
Do you mean "what is velocity?" If so, velocity is the distance an object has travelled in a specific unit of time. The SI units for velocity are m/s. Note that velocity is a vector; a vector must have a direction. Therefore, velocity is a speed in a given direction. Do not confuse velocity with acceleration, as acceleration is the change in velocity from two points in time. The units for acceleration are m/s^2.
