Question

Mohammed made a chart to list examples and nonexamples of projectile motion.

A 2 column table with 1 row. The first column is labeled Projectile Motion with entries an arrow shot from a bow, a soccer ball kicked by a player. The second column is labeled Not Projectile Motion with entries a cart pushed up a ramp, unknown.

Which best completes the chart?

a football thrown in the air
a kite flying on a string
a golf ball rolling off a table
water spraying from a fountain

Answer 1

a kite flying on a string

Reason: projectile motion means an object moves only under the influence of gravity (ignoring air resistance). A kite is held by a string and lifted by aerodynamic forces, so it is not a projectile.
