To calculate the of a moving object, divide the displacement by the time interval in which the displacement occurred.

Speed

Explanation: Scalar quantity is the quantity that only possess magnitude but no direction.

Vector quantity is the quantity that only possess magnitude as well as  direction.

Speed is defined as the displacement of an object per unit time and is a scalar quantity as it does not involve any direction.

Velocity is defined as the distance moved by an object per unit time and is a vector quantity as it deals with magnitude as well as direction.

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.
