Laws of Motion
An object in motion will remain in motion. An object at rest will remain at rest, unless an outside force acts upon it.
What is Newton's first law?
A plane travels 530 miles on its flight. (name the characteristic that matches)
What is distance?
Speed in a given direction (refers to the length, time, and direction)
What is velocity?
The scientist that developed the three laws of motion.
Sir Isaac Newton
Relies on both mass and velocity.
What is momentum?
Every action has an equal and opposite reaction.
What is Newton's 3rd law?
A cheetah runs 18mph. (name the characteristic is matches)
What is speed?
A change in velocity during a period of time.
What is acceleration?
The two types of mechanical energy.
What is kinetic and potential energy?
The force that keeps objects from moving against other objects.
What is friction?
You are riding a bicycle. You hit a rock and fly forward. This is an example of ...
What is Newton's 1st law?
Found by dividing the distance traveled by the amount of time it takes to travel that distance.
What is speed?
The car can reach 45 mph in 5 seconds.
What is acceleration?
The ability to do work.
What is energy?
Any change in an object's motion depends directly on the applied force and indirectly on the mass of the object.
What is Newton's 2nd law?
What is distance?
The faster this changes, the greater the acceleration.
What is velocity?
The scientist and philosopher who first developed ideas about motion; thought that objects contained something within them that gave them the potential to move.
Who is Arisotle?
The tendency to keep moving because of mass, speed, and direction.
The ping-pong ball bounces off the paddle after the player hits in their direction.
The speed that speedometers measure; an object's speed at a particular moment.
This must be applied in order for acceleration to occcur.
What is a force?
The scientist who challenged early ideas about motion from Aristotle.
Who is Galileo Galilei?
Momentum is not created or destroyed. Without other outside forces involved, when two objects collide, the total momentum is the same before and after the collision.
What is the Law of Conservation of Momentum?
