Imagine you walk 8 blocks, then you turn back and walk 3 blocks
your position from your home is 8 - 3 = 5
your distance is 8 + 3 = 11
Using the definition of kinetic energy, we have:
Answer:
4) moves with constant velocity
Explanation:
If an object is in motion, three things can happen:
1. The object slows down in speed.
This means a net force is needed to be able to slow the object down in speed.
2. The object increases in speed.
This means a net force is needed to be able to increase the speed of the object.

No net zero unbalanced force is needed.
This is the given situation. So this is the right answer.
The region where warm and cold air masses meet is called a front
