Kinematics Flashcards
Define distance
Distance is the total length covered by a moving object regardless of direction of motion
Define displacement
Displacement is the distance measured in a straight line from a fixed reference point
Define speed
Speed is distance travelled per unit time
Define velocity
Velocity is the rate of change of displacement
What is average speed
Average speed assumes that an object moves at the same speed throughout the entire distance
Define acceleration
Acceleration is the rate of change of velocity
How to find displacement from a v-t graph
Calculate area under the graph
When can an object be in free fall
- Only force acting on it is its weight
- No air resistance
Define uniform acceleration
Uniform acceleration is a constant rate of change of velocity
What is the acceleration due to gravity
10m/s^2
