What is the process of learning that begins with a hypothesis and leads to a conclusion supported by scientific evidence?
Scientific Method
Free fall
What is the definition of a newton?
The force required to accelerate a 1kg mass 1m/s/s
The inertia is decreased.
What is are variables that are not allowed to change?
Control variables
Speed with direction is called what?
Velocity
A pulling force carried by a rope is called what?
Tension
What is an unbalanced force?
A force that is able to cause change
Position and Speed are examples of what?
Variables
What is the name of a position of 0?
The origin
Friction; static and sliding friction.
The trait in massive things to resist changes in motion is called what?
Inertia
Experimental variables that affect other experimental variables are called what?
Dependent variables
The rate at which velocity changes is called what?
acceleration
The force that the legs of your chair exert on your body is called what?
Normal Force
The relationship between the force on an object, the mass of the object, and its acceleration is described by what?
Newton's second law
A pelican flies north at a speed of 52km/h for 0.25 hours. How many meters does the pelican fly?
13km = 13,000 meters.
YES! Constant speed.
The sum of all forces acting on an object is called what?
The net force.
If the force exerted on two objects are equal, but the acceleration of each is different, what must you conclude about the masses of each?
The masses are different.
