Regents Physics Constant Velocity/ Acceleration Lab 10-3-13 Problem: Graphical Analysis of Constant Velocity and Accelerated Motion. Theory: Gravitational acceleration is constant on Earth g=9.8m/s2 Therefore‚ when the golf ball is dropped‚ the acceleration will be equal to gravitational acceleration agb=9.8m/s2 Given there is no air resistance‚ this means that when the golf ball is dropped from a given distance‚ according to the formulas‚ the golf ball will accelerate

People sometimes engage in activities and are unaware that such activity involves physics. Physics is all around. For instance‚ you may go to Six Flags and do not analyze how physics helps the machines you ride in operate. Have you ever asked yourself how a roller coaster works? Would roller coasters safely run without the knowledge that physics offers us? The answer is no. Roller coasters are driven by physics; it mobilizes and gives its riders amusement through forces such as inertia‚ gravitation

This is not very accurate data because there is air in the room too. And the doll on the parachute is always moving around when it drop‚ so the distance of the parachute is not very accurate. Conclusion: In this lab‚ we have changed our IV and DV after we done the first time lab because we can’t measure the air

tested on the angle board. 2. As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface and a perpendicular to the surface at the point of incidence. Angle of reflection is the angle between the reflected ray and the normal ray.

Discuss Alan’s criminal liability for his statement to Bhu‚ “We sort out thieves like you.” (7 marks) I think that Alan would be trialled for assault under s. 47 of the Offences Against the Person Act 1861. This crime cannot be battery as no force has been used‚ neither can it be GBH or ABH as no wounding or injury has been caused. Assault offences can be done by: silence alone- as shown in the case of

MOMENTUM QUESTIONS 1. Which has greater momentum: a train at rest or a moving skateboard? Since the train is not moving‚ it has zero momentum. The skateboard‚ as long as it has some speed‚ will have more momentum‚ since p = m*v. 2. What are the ways to increase impulse? Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those‚ impulse on a system will be increased‚ and the system’s momentum will change accordingly
