Newton's first law is that an object at rest stays at rest and an object in motion stays in motion.
What is the Newton's Frist Law?
100
force
What is the opposite of friction?
100
mass is a measure of the amount of matter in an object and weight is the force of gravity on a force or an object.
What is the difference between weight and mass?
100
the third law of motion
which of newtons three law of motion explains how a rocket lifts off?
100
any object that orbits another object in space.
What is a satellite?
200
Acceleration is equal to net force
What is Newtons Second Law?
200
static friction, sliding friction, rolling friction, fluid friction
What are the four types of friction?
200
Newton.
What is mass and weight measured in/
200
centripetal force.
what type of force causes an object to move in a circular path?
200
centripetal force
What keeps a satellite in orbit?
300
an unbalanced force
objects only move with what kind of force?
300
how hard the surfaces push together and the types of surfaces involved.
What are the two factors that friction depends on?
300
the gravitational force will be greater if it has more mass.
the more mass the object has, will it have a lesser and greater gravitational force?
300
gases expel with a downward action force exerted with an equal but opposite reaction force on the rocket.
how does a rocket lift off the ground?
300
Earth
satellites in orbit around earth continuously falling towards what?
400
for every action, there is an equal and opposite reaction.
what is Newton's third law of motion?
400
mass and distance
What are the two factors that affect the gravitational attraction between objects?
400
yes
Does weight vary with the gravitational force?
400
thrust
What is the upward pushing force called?
400
satellites
What orbits the earth?
500
third law of Newton
What Newton's law used how to explain how a rocket takes off.
500
when the only force acting on an object or person at the surface of a planet.
what is free fall?
500
yes, the gravity will increase.
if the mass increases will the force of gravity increase?
500
downward puling
thrust is greater than a pulling of what?
500
1,000 kilometers.
satellites are put into low orbits of less than what?
