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 if the acceleration is constant.The path followed by a projectile is called

S74 Experimental Investigation Determining Acceleration in relativity to force and mass Reece Day Izaac Ellings/Lachlan Morgan 26/08/2013 Mr Fogarty 1. Introduction Background theory review Physics is defined as the study of matter and energy as well as their interactions (Lombardi‚ 2001). Although physics is more theoretical based‚ countless solutions are discovered through observation/experimentation (Physics.org‚ ?) and many seemingly intricate things in nature can

a) Distance covered by the man b) Displacement of the man c) Time taken by the man in reaching from A to B. 2. A car starting from rest moves with a uniform acceleration of 0.1 m/s2 for 2 minutes. Find the speed acquired by the car. 3. A ship is moving at a speed of 56 km/h. One second later it is moving at 58 km/h. What is its acceleration? 4. A child completes a circular track of 200 m length in 10 seconds. Calculate a) speed‚ b) velocity. 5. A car travels 10 m in 5 seconds‚ 20 m in next 10 seconds

measured for various initial angles‚ and also calculated by applying the theory for motion with constant acceleration. For further background information‚ refer to the sections in your textbook on projectile motion and motion with constant acceleration. THEORY For a given initial velocity‚ v0 ‚ and initial position‚ s0 ‚the position of a particle‚ s‚ as a function of time‚ undergoing constant acceleration‚ a is given by sr = sr 0 + vr 0 t + 12 ar t 2 ( 1 ) This is a vector equation and can be broken up

the position vector is a function of time. Velocity & Acceleration • Velocity is defined as the change in position over a change in time; thus the average velocity is and the instantaneous velocity is • For motion in one dimension the velocity is the slope of the position line plotted versus time. • The same logic is used in deriving the average and instantaneous acceleration resulting in: • Jerk is defined as the rate of change of acceleration: Example 1 • A body starts from rest at x=0. ax(t)=2t-4

of this lab is to show how to calculate the average speed and acceleration in six different races. In order to find average speed you will need to use the formula s=d/t (s= speed‚ d=distance‚ t=time). On the other hand‚ for accelaration you will use the formula a= vf-vi/t (a=acceleration‚ vf=final velocity‚ vi= initial velocity‚ t=time). Average speed is how fast something is moving; the path distanced moved per time. Acceleration is the rate of which velocity is changing‚ the change may be
