The mass is a matter contained in a body. Mass is expressed in kilogram (kg).
The weight of a body is a force by which it is attracted towards the centre of the earth. Weight is expressed in Newtons (N).
The relation between the mass and weight of a body is given by W = m.g

Explanation:
In Projectile
* A path, traced by a projectile in the space, is known as trajectory.
* The velocity with which a projectile is projected, is known as the velocity of projection.
* The angle, with the horizontal, at which a projectile is projected is known as angle of projection.
Answer is:
45 degree
Explanation:
Angle of projection: Angle of projection is the angle, with the horizontal,at which the projectile is projected.
The range of projectile is maximum, when the angle of projection is 45 degree.
