PROJECTILE PHYSICS
Scientists call things that fly through the air (like rockets) projectiles, and
they study the physics of projectiles to figure out where rockets will go when
they blast off. Some of the important questions they have to answer are:
• What kind of force does it take to start the motion of an object?
• How does that force interact with the mass of the object to affect
its speed?
• How does gravity act upon the object to affect its downward motion?
• What effect does air resistance have on the object?
COOL SCIENCE FACT: COOL SCIENCE FACT:
Mass is the amount of matter than an object contains, which is not the same thing as
weight , which is how much force that mass experiences in a certain amount of gravity.
Even though your mass doesn’t change, your weight on the moon would be much less
than your weight on Earth because the moon exerts a smaller gravitational force.
