Formulas/Calculations
The formula of displacement
What is D2-D1?
What is 'v'?
When analysing a P-T Graph, what information does the slope on the graph provide?
It provides information on the speed and the direction of an object.
How do you calculate the value of distance?
Add each value given.
The formula for calculating speed.
What is distance divided by time?
Two pieces of information you need to calculate displacement
What is the initial and final position?
The difference between speed and velocity
What is direction?
When an object moves at a consistent speed, what name corresponds to its motion?
Uniform Motion.
MJ kicks a ball. It travels 5m, hits a tree and changes direction, sending it an additional 10m to the right. What is the distance?
15m
The two things you need to calculate the velocity of an object
What is displacement and the time interval?
Since the letter 'v' is used to represent both speed and velocity, state something that differentiates the two
What is an arrow above the 'v' for velocity?
If the slope on a graph is horizontal, what does it mean for the moving object?
No movement.
Say a frog started on a lily pad at position 0 and hopped 35m north before turning back and hopping 21m to the south. Calculate the total displacement of the frog.
-14m (s)
A spider crawls 27cm north, 74cm east, and gets swatted by a broom sending it 90cm south. What is the total distance that the ant traveled?
191cm.
When a car travels at 60 km/h and it takes 4 hours to complete its journey, state the total distance the car covered
What is 240 km/h?
What is scalar?
On a graph, what variables are used to identify time and position?
The variables used to identify time and position are x and y.
Ben starts in position 2. He sprints 36m west, touches a line, and then sprints 11m to the east. Calculate the total distance and displacement of Ben’s run.
Displacement = -27m (e)
What is the time interval?
The formula for calculating velocity
What is displacement over time?
Which is the dependant variable on a P-T Graph, x or y?
Y.
If a ball is thrown 79km west and rolls back east by 28m, what is the total displacement?
-78,972m (w)
