In summary, the question was asking for the force acting on the ball during its upward movement, and you correctly calculated this force to be 1.96 Newtons using the equation w=mg. However, if the ball were in a downward movement, the force acting on it would be different.

Homework Statement


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.

Homework Equations


w=mg

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.
 

FAQ: Forces acting on a thrown object

What is the definition of a force?

A force is a push or pull on an object that causes it to change its speed, direction, or shape.

What are the different types of forces that act on a thrown object?

The different types of forces that act on a thrown object include gravity, air resistance, and the force from the thrower's hand.

How does gravity affect a thrown object?

Gravity is a force that pulls objects towards the Earth. When a object is thrown, gravity causes it to accelerate towards the ground, which affects its trajectory and speed.

What is the role of air resistance in a thrown object?

Air resistance, also known as drag, is a force that acts in the opposite direction of motion and slows down a thrown object. It is caused by the object pushing against the air molecules as it moves through the air.

How does the force from the thrower's hand affect a thrown object?

The force from the thrower's hand gives the object its initial speed and direction. It also affects the object's trajectory and how far it will travel.
