The moon is travelling at a constant speed however the gravitational force of earth causes it’s direction to be pulled slightly causing it t circle constantly around earth
why is the velocity of the moons orbit constantly changing but not it’s speed
because velocity involved speed and direction - the direction of the earth’s orbit is always changing creating a change in velocity
what would happen if the moon orbited closer to earth
the gravitational force acting on the moon would be greater
in order to keep steady orbit the speed would have to increase to counter the force
