Study Notes
Newton's Laws of Motion
- Newton's third law: "For every action, there is an equal and opposite reaction." This highlights the interaction of forces.
- Newton's second law: The relationship between net force, mass, and acceleration is defined by the equation F = m × a.
- An object at rest will not change its state unless acted upon by an unbalanced force, demonstrating the concept of inertia.
Key Concepts of Force
- Net force: The overall force acting on an object; if zero, the object remains at rest.
- Force: Any push or pull that can alter the motion of an object, dependent on mass and acceleration.
- Balanced forces: Forces that result in a net force of zero, keeping an object either at rest or moving at a constant velocity.
- Unbalanced forces: Cause an object to change its state of motion.
Types of Friction
- Static friction: The force resisting the initiation of motion between two surfaces at rest.
- Sliding friction: Occurs when two surfaces slide against each other; causes moving objects to slow down.
Gravitational Concepts
- Gravity: The universal force that attracts objects toward each other, directly proportional to their masses and inversely proportional to the square of the distance between them.
- Weight: The force of gravity on an object, measured in newtons, varies with gravitational strength.
- Grams and kilograms are units of mass; newtons measure weight.
Motion and Acceleration
- Terminal velocity: The maximum velocity a falling object can reach, where forces of gravity and air resistance balance.
- Acceleration: Describes how velocity changes over time; influenced by net force acting on an object.
Air Resistance and Motion
- Air resistance: The force exerted by air against a moving object, which increases with velocity.
Gravity and Distance
- The gravitational force between two objects depends on their masses and the distance separating them; closer objects exert a stronger gravitational pull.
