Physics Forces and Motion 1.1 - 1.3 Flashcards
What is speed
Speed is the rate of change in an objects position
Speed formula?
Distance/Time
What is velocity
Velocity is speed with direction
Velocity formula?
Displacement/Time
What is distance
Distance is how much an object has moved from its original or initial position
What is displacement?
Displacement is distance with direction
What is acceleration
Acceleration is how quickly something speeds up or slows down
What is the acceleration formula if given time
a = v-u/t
What is the acceleration formula if given distance
2as = v^2 - u^2
What formula will you use if given only the final velocity and told to find the distance from which an object was dropped?
2as = v^2 - u^2
What does a diagonal straight line represent in a distance time graph?
It represents a constant speed
What does a curved line represent in a distance time graph?
It represents changing speeds
What does a straight line with no gradient represent in a distance time graph?
It means that the object is stationary or isn’t moving
What is the gradient at a certain point in the curve equal to
The gradient at a certain point on the curve is equal to the speed of that certain point
