Experiments
In this experiment we put balloons onto a paper car and then blew the balloon up to watch the car move. This experiment showed us which Newton's law?
Newton's 3rd law of motion
Who discovered Newton's laws of motion?
Sir Isaac Newton
What is energy?
The ability to do work.
A ramp is an example of what simple machine?
inclined plane
How many steps are in the scientific method?
5
In this experiment we made cups fly by wrapping a rubber band around them and flinging them into the air. What made the cups fly?
Changes in air pressure
What is Newton's first law of motion?
An object in motion tends to stay in motion and an object at rest tends to stay at rest, unless acted upon by an outside force.
What is kinetic energy?
energy that is in motion.
How many types of simple machines are there?
6
Question
In this experiment we blew a ping pong ball and a rubber ball through a straw. We found that the ping pong ball went much further than the rubber ball. Which of Newton's laws did this demonstrate?
BONUS 100: Whats the formula for this law?
Newtons 2nd law
F=ma (force=mass x acceleration)
What is Newton's third law of motion?
For every action there is an equal and opposite reaction.
What is force?
Any push or pull on an object.
work
What does hypothesis mean?
an educated guess or a theory.
In this experiment we put a basketball inside of a wagon and pulled the wagon. When we stopped the wagon suddenly, the ball rolled to the front of the wagon. This demonstrated which of Newton's Laws?
Newton's first law of motion
What is Newton's 2nd law of motion?
Force equals mass times acceleration. (An objects mass will determine how much force it takes to make the object accelerate.)
What is potential energy?
stored up energy
Name all the simple machines.
screw, wedge, lever, pulley, inclined plane, wheel and axle.
What is the third step in the scientific method?
experiment
In this experiment we pushed toy cars on different surfaces. When the car was pushed on the wash cloth it went the slowest. What force caused the car to move slower?
Friction
What is another name for Newton's first law of motion?
The law of inertia.
What is Physics?
Physics is the study of matter and its motion and behavior through time and space.
Name the 3 parts of a lever.
Load, effort, fulcrum
