Study Notes

Speed and Motion

Speed is computed as the ratio of distance to time, measured in meters per second (m/s).
Average speed is defined as total distance divided by total time, also expressed in meters per second.

Distance and Force

Distance can be calculated using the formula: speed multiplied by time, which is measured in various units such as meters, centimeters, or miles.
Force is determined by multiplying mass and acceleration, with units in Newtons (N). One Newton is equivalent to a kilogram meter per second squared (Kg·m/s²).

Acceleration and Work

Acceleration represents the change in velocity over time and is calculated by dividing force by mass, rendered in meters per second squared (m/s²).
Average acceleration is found by subtracting initial velocity from final velocity and dividing by time.
Work is calculated as the product of force and distance, measured in Joules (J). One Joule is defined as one Newton meter (N·m).

Power Concepts

Power can be expressed as force multiplied by distance divided by time, yielding Joules per second, which is also known as a Watt (W).
Alternatively, power can be calculated as work done per unit of time.

Newton's Laws of Motion

Newton's First Law states that an object will remain at rest or in uniform motion unless acted upon by a net external force, also known as the Law of Inertia.
Newton's Second Law relates the force exerted on an object to its mass and the acceleration produced.
Newton's Third Law posits that for every action, there is an equal and opposite reaction.

Types of Forces and Motion Dynamics

Three primary types of forces are recognized: contact force, gravitational force, and friction.
Forces influence motion, determining the acceleration of objects.
Mass is defined as a measure of inertia, which is the resistance to changes in motion.
Forces can result in the alteration of direction while maintaining constant speed, indicating dynamic motion.

Force Characteristics

Balanced forces result in no net force acting on an object, leading to a state of rest or uniform motion.
Centripetal force is directed towards the center of a circular path, maintaining circular motion.
The acceleration due to gravity on Earth is approximately 9.8 m/s².
