What is another name for Newtons first law?
What is the law of inertia.

What is gravity?
What is a force of attraction between objects due to their mass.
200
What is potential and kinetic energy?
What is the energy of motion and the stored energy that an object has.
200
What is a reference point?
What is a location to which you compare other locations.
200
What is force?
What is a push or pull.
200
What is an example of Newton's first law?
What is a golf ball on a tee then gets hit.
200
Does every object exert a gravitational pull?
What is yes.
300
Does a sky diver about to jump off a plane have potential or kinetic energy?
What is potential
300
What is speed and how do you find it?
What is a measure of how far something moves in a given amount of time. s=distance/time
300
What is inertia?
What is the tendency of all objects to resist any change in motion.
300
How does an airbag in a car represent Newton's first law?
What is the person is stopped by the airbag.
300
What is free fall?
What is when gravity is pulling an object down and no other forces are acting on it.
400
What is mechanical energy?
What is the kinetic energy plus the potential energy due to position.
400
What is motion?
What is a change in position over time.
400
What is an example of a non-contact force?
What is jumping up because gravity pulls you down.
400
What is the second part to Newton's first law?
What is an object in motion maintains its velocity unless it experiences an unbalanced force.
400
Why doesn't a satellite fall to Earth but stays in orbit?
What is it stays in a forward orbit and it is in free fall.
500
What does the law of conservation energy state?
What is energy that can neither be created nor destroyed.
500
What is vector?
What is a quantity that has both size and direction.
500
What is acceleration?
What is the rate at which velocity changes.
500
What is Newton's second law?
What is the acceleration of an object depends on the mass of the object and the amount of force applied.
500
Why is "the moon does not fall to Earth because of friction," not true?
What is the force keeping the moon orbiting is gravity
