WHY PHYSICS IS IMPORTANT IN OUR LIVES?

WHAT IS THE SCIENCE OF PHYSICS?

Doing exercise helps your heart and breathing muscles to get strong.

Everything that respires releases heat energy.

Living cells need energy to stay alive, they get their energy from starch.

Nicotine is a:

From the process of respiration the cells produce as waste product:

The branch of science concerned with the nature and properties of matter and energy.

Alveoli are inside the lungs

A BALL IS FELL FROM REST ON A TOWER: A) WHAT IS THE SPEED OF THE BALL 23.7 SECONDS LATER, B) HOW FAR TRAVEL IN THIS TIME

When the gas exchange takes place, the alveoli takes out the carbon dioxide

THESE ARE "SOME" OF THE SEVEN FUNDAMENTAL SI UNITS USED IN PHYSICS

This substance causes lung and other kinds cancer

You can easily quit smoking because nicotine is not addictive.

A WATERMELON FALLS FROM REST FROM A HIGH TREE, IT TAKES 37.91 SECONDS TO SQUASH ON THE GROUND, HOW TALL IS THE TREE??

The organs that help to get oxygen from the air into the blood, and get rid of the carbon dioxide make up the:

For measuring temperature, we use Kelvin degrees.

Organs that made up the respiratory System

In the SI measuring system, the unit we are going to use for measuring the amount of substance is?

A ROCK IS THROWN DOWNWARD FROM A TOWER AT 15.7 M/S WHAT IS THE SPEED OF THE ROCK 8 SECONDS LATER?

The cells in our body use oxygen for respiration.

Aerobic respiration is the release of energy from glucose by reacting it with oxygen inside living cells.

A fit person has a circulatory system that can get oxygen and starch to the muscles quickly.
