700 N
1400 N
7 N
70 N

This diagram shows three models that represent the gravitational force, F, between objects.
Which model is displaying the most gravitational force of attraction?
Model 1
Model 2
Model 3
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
What is the formula to calculate Weight from mass(m) and gravity (g) ?
mass (m) / gravity (g) = weight
mass (m) + gravity (g) = weight
mass (m) - gravity (g) = weight
mass (m) x gravity (g) = weight
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
Newton's Universal Law of Gravitation claims that the attraction between objects with mass depend on what 2 things?
volume and height
velocity and height
acceleration and mass
mass and distance
