while you are in class, your iclicker falls off your desk to the floor. what forces are acting on your iclicker as it falls to the floor?

Gravitational forces and drag forces

Explanation:

All objects that are above a certain distance above the ground has gravitational force acting on them. A falling body like the iclicker has gravitational force pulling it down with a magnitude proportional to its mass and the acceleration due to gravity. As the iclicker fall, it experiences air resistance due to the drag forces on it from the air molecules around. This drag force acts upwards so as to oppose the motion of the iclicker downwards, and the magnitude is minimal when compared to the gravitational force. The resultant force is therefore downwards

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

conservation of mass

mass before something happens = mass afterwards
