Directions: Select whether the statement is true of false. 1. As the ball rises, it decreases its vertical velocity.2. The projectile experiences a constant vertical acceleration due to the pull of gravity as it rises and falls.3. Collision conserved momentum.4. The total time (t’) of flight is simply double the time it takes for the projectile to rise.5. Perfectly inelastic collision is described by maximum lost in kinetic energy.6. Elastic collision happens when 2 objects stick together after collision.7. Elastic collision conserved kinetic energy.8. The time it takes to rise to its highest point is longer than the time it takes to fall. 9. Kinetic energy is conserved in all kinds of collision.10. The horizontal distance known as the range, R of the projectile is the ratio of the horizontal velocity and the total time of flight.
