Physics CP1-6 section Revision Flashcards
Forces have….
Both a magnitude (size) and a direction
What are forces measured in
Newtons (N)
Quantities that have both size and direction are…
Vector quantities
Mass measures
The amount of matter in something and does not have a direction
Acceleration
A measure of how fast velocity is changing
Acceleration
A measure of how fast velocity is changing
Momentum
A combination of mass and velocity
Speed of an object tells you…
How far it moves in a certain time
Velocity is
Speed in a particular direction
How to calculate speed
Distance (m) ÷ time taken (s) = distance travelled (m/s)
Equation to calculate distance travelled from the speed and the time
Average speed (m/s) x time (s) = distance travelled (m)
Average speed is worked out from
The total distance travelled and the total time taken
