Equations of Motion Worksheet 1. A car moving at a velocity of 25 m/s‚ accelerates at a rate of 6 m/s2. Find its velocity after 3s. 2. An object is dropped from rest. Calculate its velocity after 2.5s if it is dropped: a. On Earth‚ where the acceleration due to gravity is 9.8m/s2. b. On Mars‚ where the acceleration due to gravity is 3.8m/s2. 3. A motorbike is travelling with a velocity of 3m/s. It accelerates at a rate of 9.3m/s for 1.8s. Calculate the distance it travels in this time. 4. A Tesla

Section A How does the engine size(capacity) of a motor car relate to the acceleration of the car? Hypothesis: The acceleration of a car will increase if the size(capacity) of the engine increases. The car with the biggest engine capacity will take the fastest to reach the velocity of 60km/h from rest position. Method: 1) Arrange to use three different hatchback cars with different engine capacities‚ but

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

Sakib Khan Electric Eels – Physics The animal that is usually known as electric eel is in fact not really an eel but a freshwater species related more to the carp family or catfish family. These unique freshwater predators got their name from the immense electrical charge that they can easily generate to stun or even kill their preys and dissuade predators. Electric eels can grow extremely large which usually can reach as high as 8 foot long and weigh a great amount of 45lbs. In addition to this

November 9‚ 2014 Madison Phillips Report Submitted: November 9‚ 2014 Title: Beers Law and Calorimetry Purpose: The purpose of this experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink
