True or False. Write T if the statement is true, and F if it is false.
1.The potential energy of the object at the top is the lowest.
2.Electrical energy – sound energy is the energy transformation in a light bulb.
3.The accepted value of acceleration due to gravity is 9.8 m/s2.
4.At the peak of the projectile motion, the vertical velocity is 0 m/s.
5.Projectiles travel with a parabolic trajectory due to the influence of gravity. ____
6.The energy stored in a stretched spring is called kinetic energy.
7.The standard unit on momentum is the Joule.
8.An object with mass will have momentum.
9.A less massive object can never have more momentum than a more massive object.
10.To get the maximum range, a projectile should be projected at an angle 45º. However, in the presence of air resistance, the angle of projection for the maximum range is less than 45 º
