Question 6

Describe what would happen if, while wearing rollerskates, you pushed as hard as you could against a wall. Why does this happen?

Revolt · Accepted Answer

If, while wearing rollerskates, a person pushed against a wall as hard as he or she could, the force of the push would be opposed by the force of the wall pushing back against the pusher. Because the wall is solid and grounded, and the pusher is wearing roller skates, the pusher would end up rolling in the direction opposite to the force of the push.

Question 7

Earth's gravity acts upon objects with a steady force of __________. A. 8.9 meters per second B. 9.8 meters per minute C. 8.9 meters per minute squared D. 9.8 meters per second squared Please select the best answer from the choices provided.

D

Question 8

Describe the four main types of resistance forces.

Revolt · Accepted Answer

The four main resistance forces are objects with mass, inertia, and momentum; friction; gravity; and air resistance. Objects with mass are able to provide resistance by colliding with other objects. Friction slows objects down by providing a steady resistance when the objects are in contact with and rubbing against a surface. Gravity provides a steady downward pull towards the center of Earth's mass. Air resistance is the cumulative force provided by millions of oxygen atoms being displaced.

Question 9

When an object has its motion changed, the cause is generally __________. A. an external force B. an internal force C. an existential force D. an interval force Please select the best answer from the choices provided.
