How is terminal velocity reached by a falling object?
While an object falls faster and faster, the backwards force of air resistance will increase. Once the force of air resistance equals the force of gravitation, the object will no longer accelerate, and is said to have reached "terminal velocity".While an object falls faster and faster, the backwards force of air resistance will increase.

How can pulleys be used to reduce the force in lifting up an object?
They convert distance into force. So putting a pulley on a load would result in you having to haul up twice as much rope, but lifting about half of the weight of the load. Multiple pulleys increase rope length and further decrease force required to move the load.
What does a pulley do to the direction of a force?
Pulleys change the direction of a force.
Ratio of resistance force to effort force?
resistance force
Describe two things you can do to increase the acceleration of an object?
Increase the force on the objectDecrease the resistance to motion (lubricate, remove resisting stuff like the air...)
How is IMA determined for pulleys?
IMA for pulleys is the resistance force divided by the effort force.

What type of pulley would increase the output force?
A pulley system that has multiple pulleys in line with each one having its output drive the next will increase the force. This would be called a tackle pulley.
Which class of lever can be to ased to increase the force applied to the resistance?

What is the function of a lever?
is to apply leverage To increase the resistance that can be moved with a given effort, e.g. a crowbar. To increase the velocity at which an object will move with a given force, e.g. a Golf club.

How can pulleys change direction of the force?
yes
Example to lift a force upward we use 2 pulleys. Then the force becomes half of the force we will have to use with one pulley.HOW?

Is air pressure a push or pull force?
Yes resistance would be a push force.
