Work and power
If an object used 87 Newtons of force over 5 meters how much work did it do?
435 Joules
If an object covered 500 Km in 3 hours what is its speed?
166.67 Km/h
What is an objects kinetic energy if it weighs 5 kg and is moving at a speed of 8.7 m/s?
189.2 Joules
What are the units for momentum and impulse?
Momentum= kg*m/s
Impulse=N-S
Who wrote the song "That's so true"?
Gracie Abrams
If an object did 200 Joules of work in 10 seconds how much power was used?
20 watts
What are the formulas for speed and velocity?
Speed= Distance/time
Veloctiy= Displacement/time
If an object weighing 87 kg falls from 67 meters what is its GPE? (Use 9.8 as your g)
57,124.2 Joules
What is the formula for momentum?
Momentum=mv
What is the most listened to phonk song?
Metamorphosis
What are the two SI units for work?
Joules and newton-meters/ N-m
What are three ways an object's acceleration changes?
An objects acceleration changes if the object speeds up, slows down, or changes direction.
True or false?
Energy can be created or destroyed
False
Define momentum and impulse in your own words.
Momentum is how much force is required to stop an object when it is in motion.
Impulse is a change of momentum
Who won the 2022 Fifa world cup?
What is the formula for work and power?
Work=Fd
Power=w/t
Define Velocity, speed, and acceleration
Velocity is a measure of speed in a certain direction.
Speed is the distance covered in a certain period of time.
Acceleration is how fast an objects slows down, speeds up, or changes direction.
What is the formula for KE and GPE?
Ke=1/2mv^2
GPE=mgh
If an object weighing 87 kg is moving 8.7 m/s what is its momentum?
756.9 kg m/s
Who was the 4th president of the United States?
James Madison
What is the definition of power and work in your own words?
Power is a measure of how quickly work is done, or the amount of work per unit time.
Work is done when a force causes an object to move over a distance.
Is velocity a scalar or vector quality?
Vector quality
How does Potential energy transfer to kinetic energy? use a real world example
answers may vary; however they should sound like maximum potential energy and minimum kinetic energy at the top, equal amounts of potential and kinetic energy halfway, and maximum kinetic energy and minimum potential energy at the bottom.
If an object is kicked with 250 N of force over a time of 0.087 seconds what is its impulse?
21.75 N-S
United States
