When you jump out of a plane to go skydiving 🪂 you thankfully have a parachute so you can safely land 🛫. Which answer choice explains why the parachute helps you land safely?
A.While gravity pulls you down very quickly, Air Resistance pushes back against gravity and your parachute, slowing you down
B.While gravity pushes you down very slowly, Air Resistance (fluid friction) pulls back against gravity and your parachute, which means you can land safely
C.When you have a parachute gravity is not able to pull you down as fast as it normally can
D.The parachute will get caught on something on your way down which will save your life

D.SOH CAH TOA is useful in determining forces on incline.
How is gravity affected by mass?
A.the larger the mass of the object, the greater the gravity
B.small objects have no gravity
C.gravity is not affected by mass of objects, whether large or small
Which of the following is a TRUE statement regarding springs?
A.The higher the value of the spring constant, the stiffer the spring.
