Which travels farthest, a cannonball shot straight up, one shot 45 degrees above the horizontal, or one shot horizontally?

A cannonball was shot at a 45 degree angle above the horizontal, and is now flying toward a castle. Check all the forces that will determine whether it hits the castle wall.

The quarterback kicks a football from the 20 yard line, and the ball just clears the goal. To celebrate, the QB runs into the endzone and throws his helmet straight up. The helmet goes just as high as the goal. Which object was in the air longer?

If you launch a ping-pong ball and a golf ball at the same initial velocity, which will travel farther? Hint - the two balls are the same size and have the same air resistance, but the ping-pong ball is MUCH lighter.

If you have a flat sheet of paper and you want to toss it into a wastebasket, it helps to crumple it into a ball. Why?

in physics, a "simple projectile" is something that flies like a rock. We can ignore air resistance, and it doesn't have wings. Check all of the things that are simple projectiles.
