Describe the four main types of resistance forces.

Following the Free-body Diagram, these are the Four types of Resistance Force with descriptions:

1. Applied Force - if a person is pushing the table across the hall, then an applied force is acting on the table.

2. Frictional Force - if a book slides across the surface of the table, then the table exerts a frictional force in the opposite direction of its motion.

3. Normal Force - if a stone is resisting upon the floor, then the floor is exerting an upward force upon the stone in order to support the weight of the stone.

4. Gravitational Force- all things on Earth experience gravity or the downward  force towards the center of the Earth. It makes all object that are thrown upward will make the objects to fall down.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
