Prevents movement by external forces ___Decelerates movement ___Causes the body part to move against gravity or external forces ___Joint angle changes in the direction of the applied muscle force ___Muscle gradually lessens in tension to control the descent of resistance ___ Accelerates movement ___Muscle force < resistance ___Muscle tension acts to maintain joint angle in stable position ___Muscle develops enough force to overcome applied resistance or gravity ___Joint angle changes in the direction of the resistance or external force ___Muscle force > resistance

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

the answer is a)

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.
