The speed at which an object is moving in a specific direction is its
A
speed.
B
acceleration rate.
C
velocity.
D
mechanical potential energy rate.
C
The answer is D
C
vector has magnitude and direction
speed is a scalar. only has magnitude
velocity is a vector, speed AND direction
The correct answer is C) velocity.
To determine the velocity of an object, you need to know both its speed and the direction in which it is moving. Velocity is a vector quantity, meaning it has both magnitude (the speed) and direction.
To calculate velocity, you can use the following formula:
velocity = displacement / time
Here's how you can determine the velocity of an object:
1. Measure the displacement or distance traveled by the object.
2. Measure the time it takes for the object to travel that distance.
3. Divide the displacement by the time to calculate the velocity.
It's important to note that velocity is different from speed. Speed refers to how fast an object is moving, while velocity includes both speed and direction. So while an object may have a high speed, its velocity will depend on the direction it is moving.
