Motion Flashcards
What is the equation for speed?
Distance
Time
What is the SI units for speed?
m/s
What is the speed of an object?
The distance travelled in a given amount of time
When does acceleration occur?
When the velocity of an object changes
What does acceleration consist of?
Starting Stopping Speeding up Slowing down Changing direction
Give the symbol equation for acceleration
a = v - u
t
What is the equation for kinetic energy?
2
0.5 x mass x speed
How do you work out the gradient?
Change in y
Change in x
In a speed time graph what does the gradient show?
Acceleration
What is the equation for velocity?
Displacement
Time
What does the gradient show in a distance time graph?
Speed
What does the gradient show in a displacement time graph?
Velocity
What is the area underneath a velocity time graph equal to?
Displacement
When an object is release close to the Earth’s surface, what is its acceleration and what is it called?
Acceleration due to gravity/acceleration of free fall
