Use the PhET Projectile Motion simulation https://phet.colorado.edu/en/simulation/projectile-motion

Assume no air resistance throughout this lab simulation.

1. Mass of objects: Golf ball vs car

Which will remain in the air longer (Time)? Provide answers below.

Expectation: Golf ball ______ Car ______ Same time ______

Explain your reasoning:

1. Range: Golf ball vs car at the same initial speed and launch angle

Which will fly further (Range)? Provide answers below.

Expectation: Golf ball ______ Car ______ Same distance ______

Explain your reasoning.

1. Height: Golf ball vs car at the same initial speed and launch angle

Which will fly higher (Height)? Provide answers below.

Expectation: Golf ball ______ Car ______ Same distance ______

Explain your reasoning.

1. An object is being shot with the same speed but with different launch angles of 65%, 45%, and 30%.

Which angle will result in the furthest distance? Rank the results with the numbers 1, 2, and 3. (1 for the furthest) below.

Expectation: 65 ______ 45 ______ 30 ______

Explain your reasoning.

1. An object is being shot with the same speeds but with different launch angles of 65, 45, and 30.

Which angle will result in the highest projectile motion? Rank the results with the numbers 1, 2, and 3. (1 for the highest).

Expectation: 65 ______ 45 ______ 30 ______

Explain your reasoning.
