Elastic Collision
A collision where kinetic energy is conserved along with linear momentum.
Inelastic Collision
A collision where kinetic energy is not conserved, but linear momentum is conserved.
Conservation of Linear Momentum
The total momentum before a collision is equal to the total momentum after the collision.
Kinetic Energy Conservation
In elastic collisions, the total kinetic energy before colliding is equal to the total kinetic energy after.
Projectile Motion
A two-dimensional motion of an object under the influence of gravitational force only.
Time of Flight
The time taken by a projectile to go from the point of projection to the point of impact.
Range of a Projectile
The horizontal displacement of a projectile from the point of projection to the point of impact.
Gravitational Acceleration
The acceleration of a freely falling body due to gravity, approximately 9.81 m/s².
Isolated System
A system where the total external force acting on it is zero.
Linear Momentum
The quantity of motion possessed by a body, calculated as the product of mass and velocity (P=mv).
