7. Kinematics Flashcards
1
Q
Distance
A
The total length covered by a moving object regardless of the direction of motion.
2
Q
Displacement
A
The distance measured in a straight line from a fixed reference point.
3
Q
Speed
A
The distance travelled per unit time.
speed = distance travelled/time taken
4
Q
Velocity
A
The rate of change in displacement
velocity = displacement/time taken
5
Q
Acceleration
A
The rate of change of velocity.
acceleration = change of velocity/time taken
6
Q
Free Fall
A
An object is said to be in free fall if the only force acting on it is the weight (no air resistance)
Object free falling experiences uniform acceleration
Regardless of mass, velocity increases at a uniform rate.
Acceleration due to gravity, g=10m/s^2
