Report all equations in a proper mathematical format, with the correct signs and symbols.
Submissions with incomplete or improperly formatted responses may be rejected.
Pre-Lab Questions
1. What is the acceleration of a ball that is vertically tossed up when it reaches its maximum
height?
At its highest point, the acceleration equals the acceleration caused by gravity acting downward,
or around 9.8 m/s².
2. Describe what the slopes of a position vs. time graph mean in relation to velocity.
An object's velocity is indicated by the slope of a location vs. time graph. A positive slope
corresponds to a positive velocity, which denotes mobility in a positive direction. On the
other hand, travel in the opposite direction is implied by a negative slope. An object that
slopes horizontally is momentarily at rest. Recall that faster changes in motion are
represented by steeper slopes.
3. State the 1D and 2D kinematics equations you will use in this lab in variable form. (Do not
state equations that you will not use.)
1D Kinematics Equations:
Position as a function of time:
x = x0 + v0t + (1/2)at^2 Equation of velocity: v = v0 + at.
Equation for final velocity squared: v^2 = v0^2 + 2a(x - x0)
The formulas for the 2D horizontal position equation are as follows: x = x0 + v0x t + (1/2)ax t^2.
2D Kinematics Equations (for projectile motion):
Vertical motion
Vertical position equation: y = y0 + v0y t + (1/2)ay t^2 Horizontal velocity equation: vx = v0x +
axt Vertical velocity equation: vy = v0y + ayt Final velocity squared equation: v^2 = v0^2 +2a(xx0)
