Thermal

Electrical

Chemical

Radiant/Radiation

Pitanje 2

What unit is Work measured in?

Newtons

Joules

kgm/s

Pitanje 3

The total momentum after a collision compared to the total momentum before will always be____

The same

zero

Less than

Greater

Pitanje 4

Use the Conservation of Momentum to solve the following problem:
Two ice skaters start at rest. The man pushes against the woman with a force of 10N. The man has a mass of 80kg, the woman is 60kg. Both of them slide away from each other, the woman travels at 10m/s. What is their total momentum after the push?

Pitanje 5

A rollercoaster cart can never reach a point higher than the first drop because__________

potential energy is destroyed as the cart falls

the inertia of the cart won't be able to overcome the momentum

gravity is always pulling objects down towards the Earth

friction will convert kinetic to Thermal Energy
