(Forces 1)
How many variables can be tested at one time in an experiment?
only ONE test variable or change in an experiment, more than one will result in invalid data

-----------------------.
What is stay in motion unless acted on by an unbalanced force?
A car and a large truck are rolling down a hill. Which will take more force to stop it?
The truck because it has more mass

What is 2nd
A soccer ball that was sitting still on the grass and gets kicked by a player is an example of Newton's ____ law.
What is 1st?
Define independent and dependent variables
What is the test variable and outcome variable

Erik is testing how the amount of fertilizer effect bean plants' growth. What is the Independent and Dependent?
What is I.V-amount of fertilizer
D.V-plant growth
Why would a heavier cart pushes the box farther on our videos and simulation we watched?
More mass=more applied force
According to Newton's 3rd Law,for every action _________________________.
What is an equal and opposite reaction?
System A-Two players colliding, System B-A player getting hit by a ball, System C-A player falling to the ground
Which system has the LEAST amount of total kinetic energy? Which system would have the MOST Kinetic energy and force?
LEAST-System C because the ground does not have KE (energy of motion)
MOST-System A both have more KE (due to speed and mass)
