Gravity
This scientist is famous for developing the law of gravity.
Isaac Newton
Which is impacted by gravitational force?
Weight
What happens when the North pole is facing the South pole?
The 2 poles attract each other
3. Sarah has a 3-kilogram block and a 5-kilogram block. When would a block's gravitational force on Sarah be strongest?
A. when she stands one meter away from the 3-kilogram block
B. when she stands one meter away from the 5-kilogram block
C. when she stands five meters away from the 3-kilogram block
D. when she stands five meters away from the 5-kilogram block
B. when she stands one meter away from the 5-kilogram block
This is what happens to the force of gravity as you move farther from Earth.
Decreases
If you were on the moon what would remain the same? (Weight/Mass)
Mass
What happens when the North pole is facing another North pole?
The 2 magnets repel each other.
The Moon and Earth each have a gravitational pull on each other. How would that gravitational force be affected if Earth were much farther from the Moon? A. The gravitational force would increase.
B. The gravitational force would decrease.
C. The gravitational force would be unchanged.
D. The gravitational force would cause higher tides.
B. The gravitational force would decrease.
This is what keeps the Moon in orbit around Earth
Gravity
What measurement is often used for mass? (kg, lbs, newtons, etc).
kg or grams
Rubbing a balloon on your head, making your hair stick up is an example of what type of force?
Electrical force
Which statement is a part of the Law of Gravity?
A. Earth’s gravity stops when astronauts leave the planet.
B. Objects of different mass exert the same gravitational pull.
C. Every object exerts a gravitational pull on every other object.
D. Large objects exert a gravitational pull, but small objects do not.
C. Every object exerts a gravitational pull on every other object.
Who has a stronger gravitational pull Santa Claus or the Tooth Fairy
Santa Claus
What measurement is often used for weight? (kg, lbs, newtons, etc).
Pounds (lbs)
This part of an atom carries a positive charge and is found in the nucleus. (Proton, neutron, electron)
Proton
Some trains use a system known as maglev instead of wheels. In one version of maglev, magnets inside the track act on magnets inside the train, and when the train is at full speed it never touches the ground. The magnets never touch, but the force between them can be changed by adjusting the amount of current flowing through the train’s control system. What force do these maglev trains reduce by using magnets?
A. friction
B. tension
C. elastic force
D. electrical force
A. friction
What are the two main factors that influence gravity?
Mass & Distance
Would you weigh more on Mars or Jupiter
Jupiter
This part of an atom carries a negative charge and is found around the nucleus. (proton, neutron, electron).
Electron
Which type of force requires objects to touch for a push or pull to occur?
A. a magnetic force attracting another magnet
B. a magnetic force attracting paper clips off a desk
C. the force of static electricity causing hair to be attracted to a brush
D. the force of friction slowing down a soccer ball as it rolls across the grass
