Q2. Angke of projection explain
Ans. 
Angle of projection refers to the angle at which an object is projected or launched into the air.
• It is the angle between the horizontal line and the direction in which the object is projected.

• The angle of projection affects the range and height of the projectile.

• For maximum range, the angle of projection should be 45 degrees.

• For maximum height, the angle of projection should be 90 degrees (vertical).
