Gravity Quizlet
Definition of mass
Mass is a measure of the amount of matter n an object
Weight is measured in...
Pounds (lbs) or newtons (N)
Tools used to measure weight
Scale (with springs)
Explain how gravity can keep objects static
Static objects will not move because gravity can equal to an upward force keeping the 2 forces balanced, which equals no motion
What is the law of gravitational force?
The law of gravitational force states that all objects in the universe are attracted to each other. The magnitude of the force depends on the mass of the objects and the distance away from each other.
Explain how mass effects gravity on matter
All matter has mass and gravity is affected by the mass of matter. Gravity pulls objects towards each other.
Explain how Earth's gravity affects objects on earth
Earth's gravitational force is so large, due to mass having a large mass, that it pulls all objects on earth towards the center
Mass is measured in...
Grams
What is gravity and does gravity affect motion?
Gravity is a force of attraction between objects due to their masses. Gravity can change the motion of an object by changing the objects velocity.
Explain how the distance affects the magnitude of gravitational force
If the distance of 2 objects are close then the gravity will increase Close Distance= More gravity
Explain how mass affects the magnitude of gravitational force
If the masses of 2 objects increase then the gravity will increase. More mass= More gravity
Who created the law of gravitational force and why
Issac Newton in 1665 created the law of gravitational force by watching an apple fall to the ground. He knew there had to be an unbalanced force making the apple fall. (Some say the apple hit him in the head)
Tools used to measure mass
Triple beam balance
T/F- Mass does not change if gravity changes
True
T/F- Weight changes on different planets due to change in gravity
True
Definition of weight
Weight is a measure of gravitational force on an object
