?
What is the equation for describing motion graphs?
Change of speed / time taken for change.
1 of 22
What is force measured?
Newtons (N).
2 of 22
Momentum = ?
Mass (kg) x velocity (m/s).
3 of 22
What is momentum measured in?
Kgm/s.
4 of 22
Change in momentum = ?
Resultant force x time taken.
5 of 22
What is Newton's first law of motion?
A body remains stationary or at a constant speed unless acted on by a resultant force.
6 of 22
What is Newton's second law of motion?
Force = Mass x Acceleration.
7 of 22
What is Newton's third law of motion?
Every reaction has an equal and opposite reaction.
8 of 22
How do you get a car out of a muddy field?
Slowly accelerate so that the tyres can grip, then speed up lots.
9 of 22
Decrease in GPE = ?
Increase in KE.
