Force/Motion
A push or pull is an example of a
What is a Force?
The type of potential energy found in food, gas, or batteries
What is chemical energy?
The two things required to calculate work
What are force and distance?
The rate at which work is done.
What is power?
An objects change in position relative to a reference point.
What is motion?
The units for work.
What is Joules?
The formula and unit for power.
What is Power = Work / time and Watts (W)
What is Newtons?
Work is done when a force acts on an object in the ____________ the object _________.
What is "Work is done when a force acts on an object in the direction the object moves."?
The work done to move 50 pound bags of sugar from the truck to the grocery stock room is 3241 J and it takes them 1000 Seconds to do it. What is the power required?
What is 3.241 Watts?
What is the formula and units for force?
What is Force = mass x acceleration and newtons?
The greater the amount of time taken, the __________ (larger/smaller) the amount of power involved if the work stays the same.
What is smaller?
To increase power, you can ___________ (increase/decrease) the amount of work done in a given time, or you can do a given amount of work in__________(more/less) time.
What is "To increase power, you can increases the amount of work done in a given time, or you can do a given amount of work in less time."?
How force and motion relate to work.
For work to occur, the force on an object has to be in the same direction as its motion.
Provide the formula for work. Then use the formula to answer the following question:
How much work was done? Sally moved her couch 5 m with a force of 15 newtons.
What is work = force x distance?
What is 75 joules?
A box is pushed across the floor for a distance
of 5 m with a force of 50 N in 5 seconds.
A. How much work is done?
B. What is the power?
What is 250J of work?
What is 50W of power?
