Newton’s First Law The Law of Inertia

If you were in a spaceship and fired a cannonball into space, how much force would have to be exerted on the ball to keep it moving once it has left the spaceship?

When you spin a bucket of water around in a vertical circle none of the water spills out. Use the Law of Inertia to explain why the water stays in the bucket.

Suppose you place a ball in the middle of a wagon, and then accelerate the wagon forward. Describe the motion of the ball relative to the ground. Describe its motion relative to the wagon.

How does the Law of Inertia explain how concussions happen?

A metal ball is put into the end of the tube indicated by the arrow. The ball is then shot out of the other end of the tube at high speed. Pick the path the ball will follow after it exits the tube. Note – you are looking down on these tubes, they are not vertical.

How much support force does a table exert on a book that weighs 15 N when the book is placed on the table? What if a hand pushes down on the book with a force of 20 N? What if a rope lifts up on the book with a force of 10 N? (The hand is no longer there.)

If the force of friction acting on a sliding crate is 100 N, how much force must be applied to maintain a constant velocity? What will be the net force acting on the crate? What will be the acceleration?

If suddenly the force of gravity of the sun stopped acting on the planets, in what kind of path would the planets move?
