If you stand on a scale in an elevator accelerating upward, you feel heavier because the elevator's floor presses harder on your feet, and the scale will show a higher reading than when the elevator is at rest. On the other hand, when the elevator accelerates downward, you feel lighter. The force exerted by the scale is known as apparent weight; it does not change with constant speed.

Snapshots

Details

Applying Newton's second law, the equation to link acceleration and net force is , where is your weight, is your weight measured on the scale (the usual force), and is the net force.

Snapshot 1: the elevator accelerates upward; you feel heavier

Snapshot 2: the elevator is at rest; the scale shows your actual weight

Snapshot 3: the acceleration of the elevator is downward and equal to the acceleration due to gravity; you and the elevator can be considered to be in free fall, because the scale does not exert any force

Newton's Law Lab With Predictions

In this activity you will be looking at the connection between the mass of a hover puck and the acceleration of the puck. There will be a constant force of unknown value applied to this puck. Through the completion of this activity you will determine the approximate value of this force and you will use the graph equation to make predictions about things you didn't test.

When you are ready to start the experiment, click on the begin button

Your browser does not support HTML 5.0 Canvas...get a better browser!!!

Click on the hover craft to change its mass.

Click on the hand to pull the craft across the table with a constant acceleration.
