Match the following types of motion with their characteristics:
Motion in One Dimension = Motion along a straight line Motion in Two and Three Dimensions = Motion in a plane or in space Projectile motion = Motion under the influence of gravity, with horizontal and vertical components Circular motion = Motion in a circular path, with constant speed and changing direction
Match the following concepts with their definitions:
Energy = Ability to do work Kinetic energy = Energy of motion Potential energy = Energy of position or stored energy Work = Transfer of energy from one object to another

Match the following concepts with their related laws:
Newton's First Law = Law of Inertia: an object at rest remains at rest, and an object in motion remains in motion, unless acted upon by an external force Newton's Second Law = F = ma: the force applied to an object is equal to the mass of the object multiplied by its acceleration Newton's Third Law = Action and Reaction: for every action, there is an equal and opposite reaction Law of Conservation of Energy = Energy cannot be created or destroyed, only converted from one form to another
Match the following concepts with their measurements:
Displacement = Change in position of an object Velocity = Rate of change of displacement with respect to time Acceleration = Rate of change of velocity with respect to time Gravity = g = 9.8 m/s^2
Study Notes
Kinematics
- Study of the motion of objects without considering the forces that cause the motion
- Describes the position, velocity, and acceleration of objects
- Key concepts:
- Displacement: change in position of an object
- Velocity: rate of change of displacement with respect to time
- Acceleration: rate of change of velocity with respect to time
Dynamics
- Study of the motion of objects and the forces that cause the motion
- Describes the relationship between forces and motion
- Key concepts:
- Force: push or pull that causes an object to change its motion
- Newton's Laws:
- First Law (Law of Inertia): an object at rest remains at rest, and an object in motion remains in motion, unless acted upon by an external force
- Second Law (F = ma): the force applied to an object is equal to the mass of the object multiplied by its acceleration
- Third Law (Action and Reaction): for every action, there is an equal and opposite reaction
Motion in One Dimension
- Motion along a straight line
- Key concepts:
- Uniform motion: constant velocity
- Non-uniform motion: changing velocity
- Acceleration due to gravity (g = 9.8 m/s^2)
Motion in Two and Three Dimensions
- Motion in a plane or in space
- Key concepts:
- Projectile motion: motion under the influence of gravity, with horizontal and vertical components
- Circular motion: motion in a circular path, with constant speed and changing direction
- Rotational motion: motion of an object rotating around a fixed axis
Energy and Work
- Energy: ability to do work
- Key concepts:
- Kinetic energy: energy of motion
- Potential energy: energy of position or stored energy
- Work: transfer of energy from one object to another
- Conservation of energy: energy cannot be created or destroyed, only converted from one form to another
Momentum and Collisions
- Momentum: product of an object's mass and velocity
- Key concepts:
- Conservation of momentum: total momentum remains constant in a closed system
- Elastic collisions: collisions in which kinetic energy is conserved
- Inelastic collisions: collisions in which kinetic energy is not conserved
