time between dots
in every 1 sec = 10 dots
1 dots=1/10 sec=0.1 sec
1)
2)
if speed increases keeping time constant then the spacing between the dots decreases.
3)
if frequency increases velocity increases.
4)
since the position vs time graph is linear then velocity is uniform

4. 5. Moving with Constant Acceleration, PHYS 151 1. Take several objects of different masses, but all relatively heavy, and drop them together. Do they all fall together, or do some objects fall significantly faster than others? 2. Drop a piece of paper. How is its behavior different from the others? 3 Why does the paper behave differently from the other objects? Get the timer tape (a long, skinny piece of paper with little dots on it). This was attached...
2. For each of the following motions draw a motion diagram, a position-vs-time graph, and a velocity-vs-time graph. a. A car starts from rest, steadily speeds up to 40 mph in 15s, moves at a constant speed for 30s, b. then comes to a halt in 5s A rock is dropped from a bridge and steadily speeds up as it falls. It is moving at 30 m/s when it hits the ground 3s later. Think carefully about the signs.

EXPLORE A car is moving with constant acceleration along a straight road (A) Determine how the velocity and the displacement of the car vary with time if the car is initialy moving to the right with a speed of 9.0 m/s and has an acceleration to the right of 1.7 m/s (B) Determine the velocity as a function of time when the velocity is instead initially to the right and...
2. The following velocity-vs-time graph represents the motion of a race car during the first few sec- onds of a race. The track may be assumed to be straight during this period. Afterwards the car continues to travel at a constant speed around the rest of the track, ending its lap back on the start/finish line.

Energy of a Tossed Ball In this experiment, we will study energy changes using a Motion Detector. OBJECTIVES: • Measure the change in the kinetic and potential energies as a ball moves in free fall. • See how the total energy of the ball changes during free fall. MATERIALS: Computer Lab Pro Logger Pro Vernier Motion Detector Basketball PRELIMINARY QUESTIONS (PHY2048): For each question, consider the free-fall portion of the motion of a ball tossed straight upward, starting just as...
1. What happens to the motion of an object if it has a constant
mass but you change the Magnitude of the net force on it?
Explain
2. Why did the slope change for each of the three runs? For runs

constant? What are the units for the slope for each graph?
Explain.
