Unit 3 More Acceleration

This grass hopper faces constant acceleration when it is jumping. The force of gravity is always pushing down on it, so when it jumps it is always jumping against this force. When it winds its back legs and leaps it leaps with a great velocity. As time goes on the downward acceleration slows down the velocity of its jump. Eventually causing the velocity to be zero, this is the climax or peak of the jump. After this, the grass hopper begins to fall with a negative velocity, but still the same downward acceleration of gravity. Since it is now  falling with gravity and not against it, the grass hopper picks up speed. The velocity at the end of the jump, right before landing on the ground, is the same amount of velocity that the grass hopper jumped off with. So the velocity undergoes several changes, from fast, slow, stop, start up slow, and then finish fast. The acceleration, however, remains constant the whole time because gravity is not changing.
