La representación gráfica del movimiento de un cuerpo es la que aparece en la figura. Contesta las siguientes cuestiones: a) ¿qué tipo de movimiento ha tenido en cada tramo? Razona tu respuesta. B) ¿cuál ha sido la velocidad en cada tramo? C) ¿qué espacio ha recorrido al cabo de los 10 segundos? D) ¿cuál ha sido el desplazamiento del móvil?

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

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.
