WebA projectile experiences negligible or no air resistance. A projectile must be moving in the downward direction. A projectile must be accelerating in the downward direction. A … WebOn Earth, we use the constant g = -9.8 m/s^2 to represent the constant acceleration due to gravity that pulls us to Earth's center of mass. Whether you use +g or -g depends on how you define your system; some people like to use +g and switch all their variables around. However, g always represents motion towards the center of Earth.

WebThe following steps are used to analyze projectile motion: Separate the motion into horizontal and vertical components along the x- and y-axes. These axes are perpendicular, so Ax = Acosθ and Ay = Asinθ are used. The magnitudes of the displacement s along x- and y-axes are called x and y. WebInertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia. A more massive object has more inertia than a less massive object. Fast-moving objects have more inertia than slow-moving objects.
