Scientific method
Mention the first step of the scientific method
Make an observation
Define motion.
Process of changing position.
Mention the speed formula
v= d / t
According to this Law, if the net force on an object is zero, the motion of the object does not change.
Newton's first Law
Define a renewable energy resource
An energy resource that can be replaced as fast as or faster than it is used.
What is the last step of the scientific method?
It becomes a Law
Define distance.
Length of the path taken.
Mention the acceleration formula that involves velocity
a = Vf - Vi / t
If you throw a 0.5kg ball with a force of 10N, what is the acceleration of the ball?
a= 20m/s2
Mention the formula of Power
P = W / t
What is the third step of the scientific method?
Make a hypothesis
Define displacement
Difference between the initial position and final position of an object
Mention the momentum formula
p = m . v
Define momentum
A measure of how hard it is to stop a moving object.
Write this number in scientific notation 36,000,000,000,000
3.6 x 1013
What do we do after stating a hypothesis?
Experiment
It is a measure of the distance an object travels per unit of time.
Speed
Mention the formula that represents Newton's second Law
a = F / m
According to this Law when one object exerts a force on a second object, the second object exerts an equal force on the opposite direction on the first object.
Newton's third Law
Mention 3 types of renewable energy resources
Hydroelectric, Solar, Wind (Eolic), Biomass, Geothermal
What is the definition of scientific method?
The procedure we use to answer questions about the order of nature.
A measure of the change in velocity during a period of time.
Acceleration
Mention the Work formula
W = F . d
According to this Law, the acceleration of an object is equal to the net force acting on the object divided by the object's mass.
Newton's second Law
If Panfila is running and takes 25 seconds to travel 100 meters, what is her speed?
4m/s
