explain projectile motion with its terms
Answers
Answer:
It is the motion of an object thrown and projected in the air, subject to only the acceleration of Gravity.
Projectile Motion
➡Projectile refers to an object that is in flight after being thrown or projected. In a projectile motion, the only acceleration acting is in the vertical direction which is acceleration due to gravity (g). Equations of motion, therefore, can be applied separately in X-axis and Y-axis to find the unknown parameters.
➡Some examples of Projectile Motion are
- Football
- A baseball
- A cricket ball
The projectile motion consists of two parts – one is the horizontal motion of no acceleration and the other vertical motion of constant acceleration due to gravity. The projectile motion is always in the form of a parabola which is represented as:
Few Examples of Two – Dimensional Projectiles
- Throwing a ball or a cannonball
- The motion of a billiard ball on the billiard table.
- A motion of a shell fired from a gun.
- A motion of a boat in a river.
- The motion of the earth around the sun.
