A

Air resistance decreases a skydivers rate of falling.

B

Air resistance decreases a skydivers rate of acceleration.

C

Air resistance increases a skydivers rate of acceleration.

D

Air resistance stops a skydivers from falling.

What is the force of gravity on a 50 kg object on Earth's surface, where the force due to gravity is approximately 9.81 N/kg?

If a person has a mass of 70 kg and is standing on the surface of the moon, where the force due to gravity is approximately 1.62 N/kg, what is the force of gravity acting on them?

Two forces of 5 N (left) and 8 N (right) are acting on an object in opposite directions. What is the magnitude and direction of the resultant force acting on the object?

A rock is thrown off a cliff with an initial velocity of 30 m/s. After 5 seconds it has a velocity of 79 m/s, what is its acceleration during the fall?

A car is traveling along a straight road with a constant speed of 30 m/s. If the engine provides a driving force of 5000 N, and air resistance provides a drag force of 2000 N in the opposite direction, what is the resultant force acting on the car? Calculate and explain what other force is acting on the car.

A cyclist is pedaling a bicycle on a flat road with a constant applied force of 200 N. The bicycle experiences resistive forces of 250 N. What is the resultant force acting on the bicycle? Is the cyclist accelerating, decelerating, or moving at a constant speed?
