Why does the input force have to be greater than the force needed to lift the bale?
Friction increases the effect of the input force
What is the function of the incline plane?
increases the distance an object travels, but reduces the force needed to raise the object to a higher level
What happenes to the force when the mass increases?
When the mass increases then the force also increases
How is the acceleration of a mass changes if the force applied to it increases or decreases?
Acceleration increases when force increases and decreases when force decreases.
A motorcyclist is able to ride on the vertical wall of a bowl shape track as shown does?
As the speed increases the centripetal acceleration increases. This this acceleration is caused by the normal force, then the normal force increases. Frictional force however remains equal to the weight. As the normal increases the maximum frictional force would increase. However, the amount of friction needed would still only be the rider's weight. In other words the frictional force would be less than the maximum available frictional force.

Is a backpack a balanced force?
It depends on its weight and the force of weight it is balencing out with.
How does the mechanical advantage of a wheel and axle change the size of the wheel increases?
As the size of the wheel increases the necessary force needed to pull the wheel decreases

When the mass increases then the force also increases

Acceleration increases when force increases and decreases when force decreases.

How does the force of graviti change with mass and distance?
as distance increases gravity's force decreases as mass increases gravity's force increases
What newtons law would carrying a backpack be an example of?
The third: every action has an equal and opposite reaction (in the simplest terms). The backpack is exerting a downwards force on the person, and the person balances this by exerting an upwards force on the backpack. If the forces weren't equal, the backpack would either fall to the ground or float above the person.
What happens to acceleration is force increases?
it increases in direct proportion to the force applied
How is the acceleration of an object affected by the force applied to it?
Acceleration increases as force increases.
