An object slides at a constant speed on a frictionless surface. What forces act on the object?

Question

What work is done?

Answer 1

Magnetics/None
You have to start thinking outside the box. Earth is your box, get out of it when you talk physics.

Answer 2

Gravity
Air resistance on the surface of the gliding object

The work done will be measured in the power to remain at a constant speed while overcoming air resistance. Take note that air resistance increases with the speed of the object. For instance, more power is required to move the object at 20 miles per hour than at 5 miles per hour.

Answer 3

a million) weight 2) path 3) vectors a and be are opposite. that may not equivalent 4) vector 6) Friction 7) cof = 6/18 = tangential/ wide-spread rigidity 8) coefficient of friction 10) fake ; in the event that they're equivalent and opposite they dont pass 11) quickly proportional 12) it is the only that reported rigidity = mass * accel 13) it is the only that reported for each action there is an equivalent and opposite reaction 14)

Answer 4

2 forces present: gravity and air resistance.

The work done is equal and opposite to the force of the air resistance acting against it. Since gravity tends to force the object down (i.e. perpendicular to the direction of motion) there is no work done due to gravity.

Answer 5

if it is frictionless the only force acting is air resistance.
