Study Notes
Motion
- Motion is the ability to change position with respect to surroundings in a given time, observed and measured with a fixed reference.
- Free fall is an example of motion with a uniform acceleration.
Aristotle's View of Motion
- He believed that heavier objects fall faster than lighter ones.
- According to Aristotle, a force would be needed to maintain constant motion.
Galileo's View of Motion
- He measured that objects accelerate at the same rate regardless of their size and mass, without air resistance.
- An object in motion stays in motion unless acted upon by an external force (HM).
- The motion of an object is due to its inertia (PM).
Laws of Motion
- The Law of Acceleration: acceleration of an object is directly related to its net force and inversely related to its mass.
- The Law of Interaction: in every interaction, there's a pair of forces acting on the two interacting objects.
Inertia
- Inertia is the tendency of an object to resist change in motion or at rest.
- An object's inertia depends on its mass.
- An object with a greater mass has a greater inertia, and an object with a lesser mass has a lesser inertia.
Types of Inertia
- Inertia of rest: an object stays in place unless somebody moves it.
- Inertia of motion: an object will continue to move at the same speed unless a force acts on it.
- Inertia of direction: an object will continue to move in the same direction unless a force acts on it.
Force and Friction
- Force is the cause of an object's motion, stop, or remaining at rest.
- The unit of force is Newton (N), where 1 N = 1 kg m/s.
- Friction is the force that opposes motion, demonstrated by a rolling marble that stops on a rough surface.
- Rough surfaces have more friction than smooth surfaces.
- Heavier objects have more friction because they are pressed harder with a greater force than lighter ones.
