3.2 Kinematics Flashcards
1
Q
What is kinematics?
A
the description of motion in terms of an objects position, velocity, and acceleration
2
Q
What is displacement?
A
change in position regardless of the path taken
3
Q
What is the equation for velocity?
A
displacement/time
4
Q
What is velocity?
A
how fast an objects position changes
5
Q
What is acceleration?
A
how fast an objects velocity changes
6
Q
What is the equation for acceleration?
A
change in velocity/time
7
Q
What is the main trap concerning acceleration on the MCAT?
A
an objects acceleration can change even if its speed is constant
8
Q
How do you know when an objects speed is increasing or decreasing in relation to acceleration?
A
acceleration points in same direction as velocity = speed increases
acceleration points in opposite direction = speed decreases
