An oblique collision occurs when two objects collide at an angle other than 0° or 180°. In an oblique collision between two objects, object 1 and object 2, the initial velocities of the objects form an angle θ.
According to the law of conservation of momentum, the total momentum before and after the collision remains constant. However, the direction of momentum changes due to the angular nature of the collision.
m1u1 + m1u2 = m1v1 + m2v2
Where m is mass, u is initial velocity, and v is final velocity.
The velocity vectors can be resolved into perpendicular and parallel components to the surface at the point of collision. The parallel components remain unchanged.
m1 u1 cosθ = m2 v2 cosφ
m1 u1 cosθ = m2 v2 cosφ
The perpendicular components are related by the coefficient of restitution (e).
m1 u1 sinθ = -m2 v 2 sinφ
m1 u1 sinθ = m2 v2 sinφ
By analyzing the momentum and velocity components along with conservation of energy, the collision dynamics like redirection, rotation, and energy absorption can be quantified. This physics analysis provides insights into preventing oblique collision damage.
