I defined gravity after looking at an apple falling from a tree. Who am I?
Isaac Newton

Define gravity.
Gravity is a force that pulls two objects together.

The third planet from the sun
Earth
100
State the 1st law of motion.
An object at rest or an object in motion will stay that way unless a force acts on it.

Name the tool Galileo used to look at the moons on Jupiter.
telescope

People believed my idea for a long, long time. Among many ideas I had, geocentric idea was one of them. Who am I?

What is an orbit?
An orbit is a path in which planets move.

This planet is also called the "red planet" because of its reddish appearance.
Mars
200
State the 3rd law of the motion.
For every action, there is equal and opposite reaction.

How would you find out how much you would weigh on the moon? (What is the calculation?)
You would divide your weight by 6.

I am famous for starting scientific experiments instead of just pondering on subjects to find answers. Who am I?
Galileo Galilei
300
Define acceleration.
Acceleration is a change in speed, direction, or both.
300
The tilted planet
Uranus
300
State the 2nd law of the motion.
An object accelerates because a force is acting on it.
300
What is the shape of most orbits?
Ellipses

I am a German scientist who lived in the same time period with Galileo Galilei. My idea helped Isaac Newton with the idea of gravity. Who am I?
Johannes Kepler

This planet's color is blue and it is named after a god of the sea. It is also the farthest planet in the solar system.
Neptune

What is the mass of the object if it accelerates at the rate of 17 m/s^2 when a force of 221 N pushed the object?
13 kg
400
How are mass and weight different?
Mass stays the same wherever you go. Weight changes depending on gravity.

I was not liked by my professor friend because I told them they were teaching wrong stuff. I found proof that supported heliocentric idea. But I was told to say that I was wrong and be on a house arrest... Who am I?
