Grade 6 - Test 3 Flashcards
what kind of force is gravity?
gravity is an attractive force
what is force?
a push and pull on an object
in tug of war, when people pull on a rope, what are they using?
force
what is gravity in terms of force?
gravity is the force that pulls things together.
what is matter
everything is made of matter, matter is anything that takes up space
what is mass
mass tells us how much matter is in an object
do objects of the same size have the same mass?
no- not necessarily
true or false: things that have more mass have stronger gravity
true
how des gravity help you to not fall off the earth?
on earth gravity pulls people and things down towards the center of the earth. gravity is pulling on everything all of the time.
if something gets more mass, does that increase the gravity pull on it?
yes
what happens when you throw a ball on earth vs. in space?
on earth if someone doesn’t catch it, it will fall because the gravity pulls it to the ground. In space it will keep going because it no longer has the gravity of earth.
true or false: the farther away objects are, the less their gravitational pull will be.
true
does a planet with ore mass/density have more gravity and weigh more?
yes
what relationship do you notice between the age and distance from the sun? (planets)
the planets further from the sun have a bigger orbit so it takes longer to make a year (orbit the sun) therefore further from the sun means lower age
True or false: force cannot change the speed or direction of an object
false. it can.
