My daughter needs vocab for Physics cause her test is tomorrow.Things like Matter and friction. She also needs the 3 laws of Physics too. Plz Help.

By the three laws, I would assume they mean Newton's Three Laws.
1st An object remains in a constant state of motion unless acted on by a net external force.
2nd The acceleration of an object is proportional to the net external force applied ( F = m a)
3rd If object A puts a force F on object B, object B also puts a force F on object A in the opposite direction.
Some vocab words that are common:
Mass
Weight (not the same as mass, why not?)
Force
Velocity
Speed (not the same as velocity, why not?)
Position
Acceleration
Momentum
Energy
Friction
Gravity
Work

first law:
things in motion stay in motion, and things at rest stay at rest.
second law:
force=mass*acceleration
third:
every action has a reaction
vocab:
force
