This is the definition of gravity
What is an attractive force between two objects with mass?
This is the name of the person who described the three laws we learned about in the Force and Motion unit.
Who is Isaac Newton?
This is the definition of a force.
What is any push or pull on an object?
Unit for Force
Newton
This is the amount of matter in an object.
What is mass?
This is the reason that gravity is stronger on the earth than on the moon.
What is that the strength of gravity depends on the mass of the object? OR What is that the earth is much bigger than the moon?
This is Newton's First Law of Motion.
What is "an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside (or more accurately an unbalanced) force."
This is the force that opposes option motion.
What is friction?
Unit for Work
Joules
The two factors at effect the strength of gravity.
What are mass and distance?
This is the direction that the arrow representing gravity always points on a diagram.
What is down?
This formula represents Newton's Second Law of Motion
What is Force (F) = Mass (m) X Acceleration (a)
This is the force that acts against a falling object. The directional arrow would be pointing upward.
What is drag?
The equation distance/time finds an objects this...
What is speed?
This is the definition of inertia.
What is the tendency of an object to stay at rest or in motion unless acted upon by an outside force.
What object hits the ground first when you drop a feather and a hammer at the same time on the moon, where there is no air.
What is both hit at the same time?
This is Newton's Third Law of Motion
What is "for every action there is an equal and opposite reaction"
This type of force produces no change of motion.
What is a balanced force?
Mass x acceleration
What is force?
An object has reached its final speed because drag and gravity have balanced out.
What is terminal speed?
9.8 m/s2
The acceleration of a falling object due to earth's gravity.
This is the amount of force that will accelerate a 1kg mass at 1m/s2....Think Unit!
What is one Newton?
This is the amount of force required to accelerate a 60kg science teacher at 2 meters per second squared.
What is 120 Newtons?
This does not have a unit
What is Mechanical Advantage?
The force that causes objects to move in a circular path.
What is centripetal force?
