Best Answer

Change in position and change in time

velocity= delta displacement/delta time

To find an object's velocity, you need to know its displacement (change in position) and the time it took for that displacement to occur. Velocity is calculated by dividing the displacement by the time taken.

The mass of the object.

To find an object's acceleration, you need its initial velocity, final velocity, and the time it takes to change from the initial velocity to the final velocity. The formula for acceleration is (final velocity - initial velocity) / time elapsed.

No, the momentum of an object is determined by both its mass and velocity. Since the objects have different masses, they will have different momentums even if they are falling freely.

To find the velocity, you need to specify a direction. If you just need the speed, the velocity is 15 km/hr. If you need the velocity including direction, you need to provide information about the direction (e.g., north, east, etc.).

To describe the velocity of an object, you need to know its speed (magnitude of velocity), direction of motion, and reference point for measuring the motion.

multipcation is used because its to find out how many things or objects you need if everyone gets a certain amount

velocity is what is known as a vector quantity. What this means is it needs both a DIRECTION and a MAGNITUDE for the velocity to be fully described. that's what you need.

You can't. The mass is irrelevant to velocity. You need the distance.

To describe the velocity of an object, you need to know its speed (magnitude of the velocity) and its direction of motion. Velocity is a vector quantity that combines both speed and direction.
