Forces acting on a thrown object

  1. Jul 28, 2017 #1
    1. The problem statement, all variables and given/known data
    A ball with a mass of 200 g is thrown vertically upwards with an initial velocity of 16.0 m/s. It is allowed to fall back to its original position. Ignore air resistance.
    Calculate the force acting on the ball during its upward movement.
    2. Relevant equations
    w=mg

    3. The attempt at a solution
    It's a really basic question, but I can't wrap my head around how or what it means by calculating force.
    The only thing I've been able to think of given the data I have is weight force, but i'm not sure if that's what the question is asking me to do?
    w=m*g
    w=0.200*9.8
    w=1.96N
    I'm so sorry for the dumb question!

    Welcome to PF!

    That is correct.

    Is it a correct answer to the question posed though? What if the ball is in a downward movement?
    Thank you for your reply!

    What do you think? Did you use the upward velocity in the calculation?

    No, but I'm confused as to whether I used the right equation to answer the original question.

    Yes, you did use the right equation to answer the original question.
