P1.2 - Motion Flashcards
What is distance? [1]
path taken between two points
What is displacement? [1]
shortest distance between two points
What is speed? [1]
distance travelled per unit time
What is the unit for speed? [1]
m/s
What is the formula for speed? [2]
V = S / T (DST TRIANGLE)
What is the formula for average speed? [2]
average speed = total distance travelled / total time taken
What does a steeper slope on a distance-time graph mean? [1]
higher speed
What does a less steep slope on a distance-time graph mean? [1]
less speed
What is velocity? [1]
speed in a given direction
What is acceleration? [2]
change in velocity per unit time
What is the formula for acceleration? [2]
A = V - U / T
What does everything in SUVAT stand for? [5]
S - displacement
U - initial speed
V - final speed
A - acceleration
T - time
What is deceleration? [1]
negative acceleration
What is the unit for acceleration? [1]
m/s^2
