A particle initially at rest undergoes rectilinear (i. e. straight line) motion with an acceleration that is constant in magnitude and direction. The velocity of the particle is which of the following? A) is constant in magnitude and direction.
B) is constant in direction only.
C) is constant in magnitude only.
D) can change in magnitude and direction.
E) is described by none of these.

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.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
