Gravity and the Formation of the Solar System

Gravity and the Formation of the Solar System

Let's see how much we know!

Multiple Choice

The amount of matter in an object is:

• Weight

• Matter

• Mass

• Gravity

Mass

• The amount of matter in an object

• Matter is any substance that has mass and occupies space.

• Measured in grams or kilograms

Multiple Choice

Weight is:

• How much matter an object occupies

• The same on Earth and the Moon

• The force of gravity acting on an object

Weight

• The force of gravity acting on an object.

• The more MASS you have, the more WEIGHT you have

Mass vs. Weight

The mass of an object will never change, but the weight will be different in different places.

Multiple Choice

Which has more weight....an apple on Earth or an apple on the moon?

• Earth

• Moon

Multiple Choice

What is gravity?

• an attractive force that exists between all objects that have mass

• how much space an object occupies

• how the universe was formed

• a song by Queen

Multiple Select

Check off the correct answers.

• Small force=small gravitational pull

• large mass=large gravitational pull

• short distance= string gravitational pull

• far distance=weak gravitational pull

Multiple Choice

When did the solar system begin to form?

• 1 billion years ago

• 4.6 billion years ago

• 2020...why not

• 2 million years ago

The Formation of the Solar System

• Began 4.6 billion years ago as a nebula

• Nebula- a floating cloud of gas, ice, and dust

• A shock wave from a nearby exploding star, caused the nebula to rotate and condense

• As the nebula rotated, gravity pulled bits of gas, dust, and ice into larger clumps which in turn pulled in more gas, dust, and ice

• The temperature and pressure was so high, the sun was formed

• The rest of the gas, ice, and dust pulled together into clumps and formed the planets and moons
