## Study Notes

### Energy and Motion

• Energy is defined as the ability to do work.
• Potential energy is characterized by being stored due to position or state.
• The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.
• Kinetic energy is the energy of motion, and an object has kinetic energy when it is in motion.
• Kinetic energy represents the energy of motion.

### Forces and Newton's Laws

• Balanced forces are forces that result in no net force acting on an object, resulting in no change in motion.
• Unbalanced forces result in a change in motion, either speeding up, slowing down, or changing direction.
• Newton's Second Law of Motion is represented by the formula F = ma, where F is the net force acting on an object, m is the mass of the object, and a is the acceleration of the object.
• According to Newton's First Law of Motion, an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
• The force of an object is measured in Newtons (N) according to Newton's Second Law of Motion.
• The mathematical formulation of Newton's Second Law of Motion is F = ma.
• Inertia is the concept that explains the tendency of an object to resist changes in its state of motion.
• The rate of change of velocity is measured in meters per second squared (m/s²) according to Newton's Second Law of Motion.
• According to Newton's Third Law of Motion, action and reaction forces act equally and oppositely on two interacting objects.
• When the force applied to an object increases, acceleration increases.
• Forces occur in pairs, according to Newton's Third Law of Motion, with one force being the action and the other force being the reaction.
• Distance vs. time graphs can be used to identify periods of rest, where the graph is a horizontal line.

### Forces and Motion

• A push is a force applied away from the body, while a pull is a force applied towards the body.
• Distance vs. time graphs can be used to understand motion by showing the relationship between distance and time.
