How Can an Object overcome Gravity ? Lesson #5 Flight

Demonstrate and describe how lift is affected by the shape of a surface.(301-17)

ID situations which involve Bernoulli’s principle (106-4)


Vocabulary
vocabulary

Airfoil – a streamlined shape

Horizontally – flat, left-right direction

Principle – is a rule of science

Bernoulli – that Swiss Guy

Lift – an upward force

Gravity – strong force that pulls everything down toward earth


How can heavy objects fly
How can heavy objects fly ?

A hot air balloon rises into the air and floats because the heated air inside it is lighter than the air around it. It is called a lighter-than-air flying device.


What is gravity lift
What is gravity ? LIFT?

Gravity is a strong force pulling down, but it can be overcome by an upward force called lift.

If the air pressure on the bottom surface of an object is higher than that on the top, lift is produced.

Page 17 in your student book. Read it. Try the paper blowing.


In the lab
In the lab

You will have a hand out and materials for three tests. We will proceed to the lab where you can conduct the experiments and do your write up on the sheet.
