What are the two types of motion a projectile has?

Answer 1

If you throw ball at an angle above horizontal, you will see the path of the ball looks like an inverted parabola. This is result of the fact that the ball's initial velocity has a horizontal and vertical component. If we neglect the effect of air resistance, the horizontal component is constant. But the vertical component is always decreasing at the rate of 9.8 m/s each second. To illustrate this, let the initial velocity be 49 m/s and the initial angle be 30˚.

Horizontal component = 49 * cos 30, Vertical = 49 * sin 30 = 24.5 m/s

As the ball rises from the ground to its maximum height, its vertical velocity decreases from 24.5 m/s to 0 m/s. As the ball falls from its maximum height to the ground, its vertical velocity decreases from 0 m/s to -24.5 m/s. Since the distance it rises is equal to the distance it falls, the time that it is rising is equal to the time it is falling. This means the total time is equal to twice the time it is falling. This is the reason that the shape of the ball's path is an inverted parabola. At the maximum height, the ball is moving horizontally. If you do a web search for projectile motion, you will see graphs illustrating this.

Answer 2

the two types of projectile motion are vertical and horizontal

Answer 3

The two motions that contribute to the path of a projectile are the horizontal motion and the vertical motion.

Answer 4

A projectile refers to an object upon which the only force acting is gravity. The shape of the path of a projectile in motion is called a trajectory.

Answer 5

Horizontal and vertical components which need to be treated independently from each other when working out either the horizontal or vertical motion.
