Study Notes

  • In uniformly accelerated motion, a body maintains a constant rate.
  • Range refers to the horizontal distance traveled by a projectile.
  • Objects in free fall undergo uniformly accelerated motion.
  • The acceleration due to gravity is 9.8 m/s².
  • A ball rolling straight down an incline demonstrates constant acceleration.
  • Uniformly accelerated motion is characterized by a constant change in velocity.
  • If a ball thrown straight up takes 4 seconds to complete its flight, it spends 2 seconds ascending.
  • A car with an initial velocity of 20 m/s accelerating at 10 m/s² will have a final velocity of 50 m/s.
  • To achieve the greatest horizontal range, a water hose should be aimed at an angle of 45°.
  • The path of a sepak takraw kicked from a height follows a parabolic trajectory.
  • A javelin thrown at the same speed will have equal ranges at complementary angles such as 30° and 60°.
  • A huge rock rolling down a slope is not a projectile.
  • A baseball hit at a 40° angle has minimum speed at the highest point in its flight.
