pulling

Explanation:

When stretching, the right way to stretch is to stretch until one feels the tension pull in the muscle. This pull is then held and sustained for a period of about 15 to 60 seconds. This considered the safest way to stretch, and it gives the muscles and connective tissue time to “reset” the stretch reflex.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
