4th - Intro to gravity and Laws of motion

Definition of gravity:

• A force that pulls you to the center of the planet or object.

• A strong way to be attached to the surface of the planet.

• The action of being in contact to the ground all the time.

• The force that push you towards the center of the planet or object.

• 
• 
• 
•

Select the best definition for the 1st law of motion

• An object moving will keep on moving. An object at rest will keep at rest.

• The heavier the object, the more force it will need to be moved.

• Every force has a reaction.

• Gravity affects all the objects on the planet with the same force.

Select the best definition for the 2nd law of motion

• An object moving will keep on moving. An object at rest will keep at rest.

• The heavier the object, the more force it will need to be moved.

• Every force has a reaction.

• Gravity affects all the objects on the planet with the same force.

Select the best definition for the 3rd law of motion

• An object moving will keep on moving. An object at rest will keep at rest.

• The heavier the object, the more force it will need to be moved.

• Every force has a reaction.

• Gravity affects all the objects on the planet with the same force.
