General Science Flashcards
_ can be defined as the capacity to do work
Energy
Power is defined as _ and measured in _.
The rate at which work is performed; watts(sometimes horsepower)
The term _ refers to the total of various pushes and pulls acting on an object
Net force
What is inertia?
The tendency of object to resist changes in their motion
Acceleration due to gravity is approximately _meters per second., not counting air resistance.
9.8
What is the formula for work?
w=fd
Work=force x displacement
What is the formula for momentum?
p=mv, where p=momentum, m=mass, v=velocity
Rewrite the formula for momentum in order to solve for mass
M=p/v
What is the formula for power?
p=w/t
Power=work divided by time
_ energy is the energy possessed by a moving object.
Kinetic
Newton’s third law of motion states that _.
For every action, there is an equal and opposite reaction.
In science, acceleration is often measured in _.
Meters per second, or m/s^2
F=ma is the mathematical formula representing Newton’s
Second law of motion
_ energy derives from an object’s position, shape, or state, rather than from its motion
Potential
A watt is defined as _.
One joule per second, or one ampere times one volt
