What do you need for an object to fly?

Back

a force to lift it

Front

What laws are fundamental to our understanding of flight today?

Back

Newtonś laws of motion

Front

What is sometimes called the law of inertia?

Back

Newtonś First Law of Motion

Front

When does an airplane take off and fly?

Back

when the outside force moves the aircraft fast enough to provide enough lifting force

Front

According to Newton’s second law of motion, an object’s acceleration is proportional to the sum of all forces exerted on it. How can you write this law?

Back

force(f) = mass(m) x acceleration(a) or F=ma
