On page 27, we wrote how we would ensure a fair test by only changing the (a)
On page 31, force of water went on the y axis.
When we analyzed data on page 33, we found that as force of the water (a) , the acceleration of the turbine (b) . We also found that as we (c) the mass of the turbine, the acceleration of the turbine (d) .
What is the definition of force?
The act or process of changing position or location
A scientific idea that states that an object stays at rest or stays in motion in a straight line
A push or a pull that causes an object to change its motion
Forces that are equal in size but act in opposite directions
What is Newton's First Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
An object will accelerate in the direction of the net force acting on it.
For every action, there is an equal and opposite reaction.
An object in motion will eventually come to a stop unless acted upon by a force.
What are unbalanced forces?
Unbalanced forces are equal in magnitude and direction.
Unbalanced forces can cause an object to start moving, stop moving, or change direction.
Unbalanced forces always act in pairs and cancel each other out.
Unbalanced forces are only present when an object is at rest.
If you push a shopping cart with more force, it accelerates faster. Which law of motion does this demonstrate?
The Law of Conservation of Energy
Newton's Third Law
Newton's Second Law
Newton's First Law
A soccer ball is lying still on the field. According to Newton's First Law, what will happen to the ball if no one kicks it?
It will start moving on its own.
It will remain at rest.
It will accelerate upward.
It will spin in place.

cannot accurately measure both variables at the same time.
needs to conduct more trials in order to get conclusive results.
cannot tell which change produced the results.
made an error in their hypothesis that needs to be corrected.
