Why must a force be exerted on an object to change its velocity?
To overcome the objects inertia
What must be present to change an objects velocity?
A non-zero net force on the body.
Two objects with the same velocity must be moving in the same?
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.
How can a supertanker have a huge momentum when it moves relatively slowly?
Momentum = mass x velocity. It is the product of the two which you must consider.Momentum = mass x velocity. It is the product of the two which you must consider.Momentum = mass x velocity. It is the product of the two which you must consider.Momentum = mass x velocity. It is the product of the two which you must consider.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
What must be included when reporting an object's?
direction

To objects with the same velocity must be moving in the same?
Same speed, same direction.
What must be present to change an objects velocity?
A non-zero net force on the body.
Do two skaters traveling in different directions at the same speed have the same velocity?
No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.
What do you need know to find an objects velocity?
The distance it travels in a caertain amount of time as well as the direction
What two objects with the same velocity must be moving the same?
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.

What causes change in velocity?
If an object's velocity changes -- if its speed increases or decreases or if its direction changes -- that means it has accelerated. For an object to accelerate, the sum of the forces acting upon it must be non-zero. So, in other words, forcechanges an object's velocity.
