Measuring Acceleration of Free Fall Flashcards
1
Q
What does the rate of acceleration of a falling object depend on?
A
The local strength of the gravitational field
2
Q
Gravitational Field Strength
A
Force per kilogram that acts on an object
3
Q
Describe an experiment to measure free fall
A
Light gates set up, a certain distance apart
Drop an object through the light gates
Repeat for different distances
4
Q
What do the light gates measure?
A
Time
5
Q
What do you measure distance with?
A
Metre rule (and set square)
6
Q
What goes on the x-axis?
A
t^2
7
Q
What goes on the y-axis?
A
Distance fallen
8
Q
What’s the gradient?
A
0.5g^2
As s=0xt+0.5at^2 =0.5gt^2
9
Q
How many repeats should you do?
A
At least 6
