A projectile is any object that is given an initial velocity and follows a path determined by the effects of gravitational acceleration and air resistance. Projectile motion is the act of projecting an object into the air at an angle when a curved path is an object follows when thrown or propelled near the surface of the earth.For example: a thrown football‚ an object dropped from an airplane‚ or a bullet shot from a gun.Projectile motion may only be used to solve mechanics problems

After that‚ the accelerations were gained by calculating the slope of Velocity VS. Time graph. The accelerations and the relationship among them in every stage are gained from the graph. Prediction It was predicted that the acceleration would be a constant‚ as long as the angle‚ θ‚ between the track and the desk did not

of design will experience three phases of apparent weight: the lifting‚ falling and braking stages. At first‚ the rider will feel heavier as the carriage accelerates. Then‚ as the velocity is constant‚ the apparent weight will equal that of the real weight. Finally‚ as the ride slows at the top‚ the decreasing velocity will result in a lighter feel. During free fall‚ riders will feel weightless‚ before experiencing a dramatic increase in apparent weight during the braking stage. As the ride climbs

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
