Mass vs Weight
100

The force that acts upon objects sitting at rest upon the ground or other objects

What is Normal Force?

100

Are there any forces acting upon an object that is not moving?

Yes, as there will always be a normal force, and gravitational force in action.

100

Does gravity change on different planets?

Yes. If we compare Earth's gravitational pull to the gravitational pull of Jupiter, we can see that Jupiter's gravity is much greater than the Earth's gravity

100

What is the smallest "planet"?

Pluto, as it is named a dwarf planet due to its size

100

If an object has a large mass, how hard will it be to stop the object while moving?

It will be extremely hard due to the fact that an increase in mass allows an object to gather more energy while moving.

200

The force that is almost always in effect, and makes objects fall

What is Gravitational Force?

200

If one object has a large mass, and another has a small mass, which object will move down a slope faster?

The large mass object will go down the slope faster, as it is experiencing more gravitational force going down the slope

200

What attributes affect Gravity?

The mass of an object and the amount of distance between the object and a planet or larger object

200

What is the current smallest planet?

Mercury, as it was the second smallest planet before scientists removed Pluto from the list of planets

200

Does the mass of an object change its weight?

Yes, as the more mass is added onto an object, the larger the gravitational pull

300

The force that stops objects moving across a large surface area

What is Frictional Force (Friction)?

300

If you drop an object on earth, is the speed of the object increasing?

Yes, as all objects on earth experience an acceleration of -9.81 m/s^2

300

What planet has a gravitational pull that almost matches Earth's gravity?

Venus, as its gravitational pull is 8.87 m/s² and Earth's gravitational pull is 9.807 m/s²

300

This orbit goes around the sun in an oval pattern, going closer at some points than Jupiter.

What is Pluto's Orbit?

300

What is the difference between mass and weight?

Mass is the overall matter of an object, and weight is the effect of gravitational pull on an object depending on its mass and distance from an object of large mass

400

The force that acts upon the center object moving in a circular motion

What is Centripetal Force?

400

If you are moving in one direction, and the direction suddenly changes, you are pushed in the direction that you were originally traveling in.

What is Inertia?

400

In space, is there any gravity?

Yes, as the planets have a constant pull on objects even after they leave the atmosphere.

400

What planets have any form of life?

Earth is the only planet that has life, but other planets have been recorded to have the ability to have life thrive. One example is Kepler 62F, which orbits in the habitable zone of the star Kepler 62

400

If two objects have the same mass, will they have the same weight as each other if one is placed on Mars, and the other is placed on the Moon?

No, as the gravity of each planet differs due to the size of the planet. In this situation, the object on Mars would have greater gravity

500

The force that acts upon objects with sides that have position neutrons and negative neutrons, making the objects move together when the opposite sides point each other

What is Magnetic and Electrical Force?

500

What happens when an unstoppable force meets an immovable object?

Nothing, as an unstoppable force and an immovable object, cannot exist at the same time

500

Where is gravity the strongest in the solar system?

On the sun, but if we were to judge gravity by the planets, then the greatest gravity would be on Jupiter

500

Can other planets hold life?

Yes, one is Kepler 62F, which orbits in the habitable zone of the star Kepler 62, and has been recorded to have Earth-like attributes

500

If my weight on Jupiter, Mars, and Earth is the same, is my mass the same on each planet?

No. If your weight is the same on each planet, then your mass has to have changed to be higher or lower before you got to another planet
