Investigation into relationship between height of fall of an object and the radius of the crater formed in sand as a result of the impact. By Ivan Cocklove Design Defining the problem and selecting the variables: I will investigate how the height from which a mass falls onto flat surface of sand affects the radius of the crater formed as a result of the impact. The height from which the ball is dropped is affecting the speed at the impact because the higher the drop‚ the longer the ball will

II Uniform Circular Motion A. Nomenclature 1. Speed – magnitude of an objects rate of motion (no direction‚ scalar quantity) 2. Velocity – speed and direction of an objects motion (vector‚ mag & direction) 3. If a car’s speed is constant but direction is changing‚ velocity is changing. 4. 2 ways to change velocity (change speed or change direction). 5. acceleration – change in speed over time (vector quantity) TWO types; a. Linear acceleration – speed

Section 2C 5. A car enters the freeway with a speed of 6.4 m/s and accelerates uniformly for 3.2 km in 3.5 min. How fast is the car moving after this time? 3.5 min = 210 s. Average speed = 3 200/210 = 15.238 m/s = ½ (v + vo). vo = 6.4 m/s. Solving for v‚ v = 2 × 15.238 – 6.4 = 24.076 m/s. 2D 1. A car with an initial speed of 23.7 km/h accelerates at a uniform rate of 0.92m/s2 for 3.6 s. Find the final speed and the displacement of the car during this time. Vf= Vi + at= 9.92m/s D x= Vot+

1) How do you calculate average speed? Average speed = Distance Time For example‚ if you have a car that has travelled 50km in 20 minutes the average speed would be 1km/2.5min. 2) A student measures the distance their rocket travels and has also recorded the length of flight. He works out the speed with the two values measured‚ and exclaims “I’ve worked out its top speed!” Discuss this statement. This is a false statement‚ the student has not worked out the rockets top speed‚ they have
