Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity.
Instantaneous acceleration of the proton at t = 3s. P6: A rocket is launched vertically from the ground with an initial velocity of 80m/s. It ascends. with a constant acceleration of 4 m/s2 to an altitude of 10 km. Its motors then fail, and the. rocket continues upward as a free fall particle and then falls back down.

Projectile Motion: good examples of projectiles are a rock thrown straight out from the top of a cliff and a ball thrown across a field. the word projectile comes from the Latin jacere meaning ‘to throw’ and pro meaning ‘forward’. projectile motion can be separated into two components; a vertical (up and down) motion and a horizontal ...

velocity = speed + direction of motion Things that have both a magnitude and a direction are called vectors. More on vectors in Ch.3. For 1D motion (motion along a straight line, like on an air track), we can represent the direction of motion with a +/– sign. + = going right .
2. Kinematics definitions. • Kinematics – branch of physics; study of motion • Position (x) – where you are located • Distance (d) – how far you have traveled, regardless of direction • Displacement (Dx) – where you are in relation to where you started. Distance vs. Displacement.
