I have a gravity test in 1st period, and I'm definitely going to fail.
Well, sit with me on the bus and I can give you a quick review!
So, to begin, gravity is the force that attracts all objects with mass towards each other. The more mass an object has, the more gravitational force it has. All objects have a gravitational force of 9.8m/s^2.
Right, and gravitational force is the force of attraction between two objects.
And the strength of the force of gravity between said objects depends on 2 factors: mass and distance.
Don't forget inertia & gravity, which combine to keep Earth in orbit around the sun.
Some examples of gravity in everyday life are a ball you throw in the air coming down again, a car coasting downhill even when you aren't stepping on the gas, and a glass you drop falling to the floor.
Objects with less mass feel more gravitational force, so they're pulled toward objects with more mass. Gravitational force pulls from each objects center of gravity.
Wow, I feel a lot more confident about gravity now. Thanks so much for your help!
