REVIEWER FOR SEMI FINAL

• Inelastic collisions

  • involve objects which separate after they collide, but which are deformed in some way by the interaction. Kinetic energy is not conserved.
• Inelastic Collision

  • It happens when the objects separate after they collide and there is deformation in some way by the interaction.
• Elastic Collision

  • It involves objects that separate after they collide.
• Impulse

  • It refers as the change in momentum.
• The law of conservation of momentum

  • This law states that, in a closed and isolated system, the total momentum of objects before and after the collision are equal.
• Trajectory

  • It is a curve-like path undertake by a projectile.
• Maximum Height

  • A maximum vertical distance reached by the projectile.
• Kinetic energy

  • It is the define as the energy of bodies in motion.
• Parabolic path

  • A sepak takraw that is kicked from a height of two meters follows a path. What kind of path is this.
• Momentum

  • Describes as the mass in motion.
