Gravity

A planet is discovered that has twice the mass of Earth but the same gravitational acceleration.

If you weigh 700 N on Earth, on the new planet you would weigh ____ N.

• 700 N

• 1400 N

• 7 N

• 70 N

Mass varies depending on where the object is located. _______________

• True

• False

• Maybe

Which System has the greater gravitational pull between the two objects?

• System 1
• System 2
• Same: there is no gravitational attraction between the two objects

Mass and weight are different. Mass depends on _____. Weight depends on _____.

• gravitational force, the amount of matter

• placement, force

• force, placement

• the amount of matter, gravitational force

Which system has the greater gravitational attraction between the two objects (if any)?

• System A
• System B
• Same gravitational attraction fro System A and System B

What is the definition of Gravity?

• the force that resists the sliding motion of two surfaces that are touching

• the force of attraction that pulls objects towards each other because of their masses

• the speed and the direction of a moving object

• the force that pushes perpendicular to the object's surface

If the mass of one of two spheres increases, how does it affect the gravity between the two spheres?

• the gravity increases

• the gravity decreases

• the gravity fluctuates

• the gravity is not affected

Gravitational force differs based on two things.

It increases with increasing ___________.

It decreases with increasing __________ .

• mass

  distance

• distance

  mass

• orbit

  displacement

• displacement

  orbit

This diagram shows three models that represent the gravitational force, F, between objects.

What do the arrows represent in the models?

• the mass of the objects

• the direction of the force

• the direction the object will be pushed

Gravity is an example of which kind of force?

• contact

• noncontact

• speed

• direction
