During photosynthesis, a plant uses radiant energy from the sun and transforms it into what type of energy?
What is chemical energy

How does an inclined plane effect the amount of work needed to move an object?
It doesn't... work stays the same. It decreases force, but increases distance. Work=force x distance

Max moved a box with 50N of force for 20m. Kali moved 30m using 20N of force with her box. Who did more work?

Max- 50N x 20m= 1000J Kali- 20N x 30m= 600J
