Motion Flashcards
Scalar
Quantities measured wit numbers and units
Vector
Quantities measured with numbers and units, but also have a specific direction
3 examples of scalar
length, temperature, time
3 examples of vector
acceleration, displacement, force
Average speed equation
distance/time
How is acceleration measured?
m/s^2
What is velocity going faster?
acceleration
What is velocity slowing down?
deceleration
How do you calculate accleration?
{final velocity - initial velocity)/time
Newton’s 1st Law
Law of inertia - keep doing what it is doing until a force is applied
Newton’s 2nd Law
Force = Mass * acceleration
Newton’s Third Law
Every action has an equally and opposite reaction
Define acceleration
change of speed or direction
What does the area under a velocity-time graph represent?
Displacement
The steeper a distance-time graph…
higher the speed
