Study Notes
Motion and Acceleration
- Kinematics is the study of motion with no reference to the forces that cause the motion
- Average speed = Total Distance / Total Time
- Average velocity = Total Displacement / Total Time
- Acceleration = (Final Velocity - Initial Velocity) / Time
- Displacement is a vector quantity that refers to the change in position of an object
- Velocity is also a vector quantity, because it has both magnitude and direction
- Speed is a scalar quantity
- Uniform Acceleration means that the velocity changes by the same amount each second
- Acceleration due to gravity near the surface of the Earth is 9.8 m/s²
Solving for Motion Problems
- Equations can be used to solve motion problems with constant acceleration.
- Use the relationship between initial velocity, final velocity, acceleration and time to solve motion problems.
- Use the relationship between initial velocity, final velocity, acceleration and displacement to solve motion problems
- The acceleration due to gravity is a constant value, g = 9.8 m/s² and does not depend upon the mass of the object
Vector Quantities
- Force is a vector
- Momentum is a vector
- Velocity is a vector
- Displacement is a vector
Scalar Quantities
- Time is a scalar
- Speed is a scalar
- Energy is a scalar
- Work is a scalar
