When a body is thrown at an angle from the base, it takes a curved path. It is known as projectile motion. The body moves to the highest point and then falls under gravity.
In horizontal direction, the body has constant velocity as no acceleration acts in this direction. In the vertical direction, acceleration due to gravity acts. Because of the combined effect, the body moves in a curved path towards the ground. The path is curved down towards the ground.
Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another.
