Students in a physics class were given several objects and asked to explore the nature of objects in free fall. The students drop each object from a height of 1.5m. They use a timer to determine how long it takes each object to hit the ground. One of the students forgets to record the data for the time it took the samples of paper to fall. Their results are presented in the table below:

The force will determine the acceleration.

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
