Physics AQA Unit 2 Quiz: Work, energy and momentum

This is my third Unit 2 quiz, covering energy, work, momentum, collisions and explosions.

?
What is the unit of work?
J
1 of 10
What is the equation to calculate work?
force applied x distance moved in the direction of the force
2 of 10
What work is done on an object if a force of 400N moves it a distance of 5m?
2000J
3 of 10
What is the equation to calculate kinetic energy?
1/2 x mass x speed squared
4 of 10
A jogger of mass 60kg runs at 3m/s. What is the kinetic energy of the jogger?
270J
5 of 10
The units of momentum are kgm/s or Ns, but what is the equation?
mass x velocity
6 of 10
A trolley of mass 0.2kg moving at 1.5m/s to the right collides with a staionary trolley of mass 0.3kg. After the collision they move off together. Calculate the velocity of the trolleys after the collision.
0.6m/s
7 of 10
What is the conservation of momentum?
Whenever objects interact, the total momentum before the interaction is the same as the total momentum afterwards, providing no external forces act

at the last question you ask for the mass but all the options are in units of Newtons so you should correct that to kg. good content, but maybe too many questions.
