Relative Velocity and Riverboat Problems On occasion objects move within a medium that is moving with respect to an observer. For example‚ an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example‚ a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land. In such instances as this‚ the magnitude of the velocity of the moving object (whether it be a plane or a motorboat)

Lab #3: Initial Velocity of a Projectile | | | Abhishek Samdaria | Pd.4 and 5 | | Lab #3: Initial Velocity of a Projectile Theory: How can we determine the initial velocity of a projectile? Experimental Design: The purpose behind this experiment was to determine the initial velocity of a projectile. Projection motion consists of kinematics of motion in the x and y directions. With two dimension kinematics‚ there are the x and y components in any given velocity. In projectile

Introduction: This lab is an experiment in terminal velocity‚ the speed an object cannot surpass due to frictional forces. To begin‚ it is important to note that the objects in this lab are not in a free-fall scenario. A free-fall scenario is a situation where an object is dropped in a frictionless environment‚ and the only force that is acting upon it is the force of gravity. In a free fall environment‚ terminal velocity would not occur‚ because no frictional forces would act on the object to

The time it takes for the ball to hit the ground depends on v0 ‚ g and h. 004 10.0 points The velocity of a projectile at launch has a horizontal component vh and a vertical component vv . When the projectile is at the highest point of its trajectory‚ identify the vertical and the horizontal components of its velocity and the vertical component of its acceleration. Consider air resistance to be negligible. 4. It cannot be determined. 002 10.0 points

Osmosis in potato cells Aim: To view and examine the effect different concentrations of sucrose solution has on the movement of water across the cell membrane. Hypothesis: That the potatoes will either increase or decrease in mass‚ due to the effect of the different concentrations. Osmosis will occur. Apparatus: * Fresh potatoes * Apple corer * Scalpel * Petri dishes X 10 * 50ml measuring cylinder * Distilled water * Paper towelling * Sucrose solutions:
