(Forces 1)
Definition for an independent variable
What is the test variable?
If the net force acting on an object is 0, then the object has a _________ 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
Definition for dependent variable
The variable that gets measured and is the outcome or the effect
This is a factor that affects kinetic energy
What is mass and speed

What is 1st?
Definition for a control variable
Variable that remains constant (the same) in the experiment

A rocket is an example of Newton's ____ law
Amaya pushes with 20 Newtons of force towards Tyler and Tyler pushes with 40 Newtons of force towards Amaya. The net force is __________ and the box will move towards ________.
20 Newtons
Towards Amaya
What is the Newton's 3rd law of motion?
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 the unit of measurement for force?
What is Newtons
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)
