It will accelerate downward under the force of gravity and hence a g. Hence horizontal distance X is given by: X Vx× t The vertical motion of the ball is also not complicated. The ball moves with a constant horizontal velocity component. Visit Circular and Satellite Motion Interactives. The horizontal motion of the ball is simple.

Most of the Interactives are accompanied by an activity sheet that suggests ways to use the Interactive. The Interactives are intended to be used by the individual student or learner who is attempting to further understand the concept or by a teacher-led classroom as part of a lesson or homework assignment. And still other Interactives provide game-like environments that require the user to use a physics concept to meet a challenge. Other Interactives are skill building exercises in which a user practices a skill that is crucial to learning some aspect of physics. Some Interactives are simulations that allow a user to manipulate an environment and observe the effect of changes in variables upon the simulation. Physics InteractivesWelcome to Physics Interactives! This section of our website features a collection of HTML5 interactive pages that allow a user to explore a physics concept. And we have incorporated our Task Tracker directly into several of the Interactives. We have generated more than 50 Concept Checkers for use with the Physics Interactives. A Concept Checker in an interactive questioning module used to access student comprehension. Task Tracker is our tool for tracking student progress on website activities. Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown with some initial velocity near the earth’s surface, and it moves along a curved path under the action of gravity alone. Solution: V 0 = 28 m/s, θ = 30 degrees (a) The maximum height = H max = ( V 0sinθ ) 2/(2 g) = (28 Sin 30)^2 / (2×9.8) m = 10 m (b) the time taken by the ball to return to the same level = Total time = T tot = 2(V 0sinθ )/g = (2x28xsin 30) /9.8 = 2.9 s (c) the distance from the thrower to the point where the ball returns to the same level = Horizontal range of a projectile = R = (V 0 2 sin2θ )/ g = (28x28xsin 60)/9.Physics Interactives with Concept Checkersīeginning this Fall, Task Tracker and Physics Interactives collide to produce Concept Checkers. Calculate (a) the maximum height (b) the time taken by the ball to return to the same level (c) the distance from the thrower to the point where the ball returns to the same level. Projectile Motion formula | equations of projectile motion Projectile Motion Solved ExampleĪ ball is thrown at a speed of 28 m/s in a direction 30 degrees above the horizontal. The initial velocity component along X-axis = V 0x = V 0 cosθ and the initial velocity component along Y-axis = V 0y = V 0sinθ. Figure 1: Projectile motion formula or equations
