I put yes because an object be accelerating at 50 m/s^2 and then decelerate to 40 m/s^2 but velocity would still increase.

2. Describe the motion of the object

V parallel to a

V anti-parallel to a

V perpendicular

I put that when V is parallel with a, it accelerates

When V is anti-parallel with a, it decelerates

When it's perpendicular, its at rest

3. Standing in a train, you throw a coin to the side, describe the motion of the coin.

I put that the coin will travel with the train and drop under where the person dropped the coin at.

4. When traveling down a flat road at a constant speed, do you feel lighter, heavier, or the same.

Going up a hill?

Going down a hill?

I put the same for the flat road, lighter going up a hill, and heavier going down.

Can anyone please check my work? I want to know how I did on an exam. Thank you.
