What is Work?
Displacement caused from that specific force force
What is Power?
The rate work is done at.
What relationship do power and time have?
Inverse
What is Force?
A push or pull on an object
A waiter bringing a plate 20 yards forwards deals work. Is this work?
No, the force was vertical and the displacement is horizontal.
Person A and B deal the same amount of work. But Person A deals it in 5 less seconds at 5 seconds, who did more power?
Person A.
Power and Work inversely related. True or false.
What is displacement?
Distance between the start and ending points
How much work was done? A person pushes a box 5 meters at 12n.
60 J or 60 N*M
How much power was dealt at 60 J of work in 3 seconds?
20 W
What is the relationship work and force have?
Direct.
What is time measured in with solving for power and other variables?
Seconds
A 24n book was added to a string that moved up 2 meters. How much work was done?
48 J or N*M
What power did an object with 400 J of work in 10s feel?
40 W
What relationship do work and time have?
Direct
How much time did a work of 300 j with 50 w of power take to do?
6 seconds
How much work does a box that is moved 20m with a force of 20n feel?
400 J or N*M
Person A deals 20 J of work in 2 seconds, and person B deals 45 J of work in 5 seconds. Person A dealt more power.
True.
What relationship do time and work have.
What force does an object with 400 j of work and 40m of displacement have?
10n.
