The work you do is 4 J.
  Indicate whether the statement is true or false



[Ques. 2] You carry a 20 N box 5 m horizontally across a room. The work you do is 100 N-m.
  Indicate whether the statement is true or false



[Ques. 3] Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t. A watt is equal to 746 horsepower.
  Indicate whether the statement is true or false



[Ques. 4] Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t. The measure of a body's resistance to being rotated is its angular momentum.
  Indicate whether the statement is true or false



[Ques. 5] Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t. The power you supply to the crate is Fd/t.
  Indicate whether the statement is true or false



[Ques. 6] Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t. The work you do on the crate is Fv.
  Indicate whether the statement is true or false



[Ques. 7] Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t. The linear momentum of the crate is Fv.
  Indicate whether the statement is true or false



[Ques. 8] Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t. The potential energy of the crate is mgd.
  Indicate whether the statement is true or false



[Ques. 9] Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t. The kinetic energy of the crate is 1/2 mv2.
  Indicate whether the statement is true or false



[Ques. 10] Consider a situation where a skater pulls her arms inward, causing her rotation rate to speed up. Kinetic energy is conserved.
  Indicate whether the statement is true or false
