Forces And Their Effects Flashcards
Why is momentum considered ‘conserved’?
The total remains the same in explosions and collisions. so long as no external force is acting on the objects involved.
CALCULATE FORCE.
Change in momentum divided by time taken for change.
Calculation for momentum
Mass X velocity
When can we calculate terminal velocity?
When the resultant force is at 0
Acceleration is measured in
M/s^2
Define speed
The rate in which someone or something is moving.
Speed triangle?
Distance(m)
Speed(m/s) Time(seconds)
Calculating momentum(triangle)
Momentum/P(m/s)
Mass(kg). Velocity(m/s)
Velocity definition
Rate in which someone or something moves in a specific direction.
What is ‘work done’?
The energy transferred when a force causes an object to move.
Calculate work done
W=FD
Acceleration triangle
Force(N)
Mass(kg). Acceleration(m/s^2)
What is potential difference?
Another word for voltage
