Method to find total area under v-t graph
Break into geometric shapes and add their areas
Can speed be negative
Can speed be negative
No, it's a scalar
Can distance be negative
Can distance be negative
No, it's a scalar
Why speed and distance cannot be negative
Why speed and distance cannot be negative
Because they are scalars (magnitude only, no direction)
Can velocity be negative
Can velocity be negative
Yes, when object moves backwards
Can displacement be negative
Can displacement be negative
Yes (can be negative or positive)
Area below x-axis on v-t graph
Area below x-axis on v-t graph
Negative value
Area above x-axis on v-t graph
Area above x-axis on v-t graph
Positive value
