04+Newtons+1st+and+2nd+Law

Group 4

TASK: Describe 1rst and 2nd law, and explain the effect they have on motion. Describe how gravity and air resistance affect the motion of free falling objects.

1. Newton's First Law-  //Every material object continues in its state of rest or motion in a straight line, unless it is compelled to change that state by forces impelled upon it.// Exemplifies inertia. Example is pulling a table cloth off a table, and if done right, the dishes stay put. Another example is jumping. When you land, you do not land were you would because the Earth had moved while you jumped. You continue with the motion of the Earth.

The greater the mass, the greater force needed for acceleration. The acceleration of the object is always in the direction of the net force.

Gravity and Air Resistance- Gravity (g) has an average value of 9.8 m/s^2. Velocity acquired= acceleration x time (v=gt). When an object is in a vacuum, the net force of the object is its weight. In an air resistance situation, net force= weight - air drag. Drag depends on the frontal area of the falling object (the greater the frontal area, the greater the drag) and the object's speed (greater speed = more molecules hit per second= greater drag)
