Physics Fundamentals

These flashcards cover the fundamental concepts related to forces, motion, and Newton's laws as outlined in the lecture notes.

What is force?

A push or pull that makes energy transform from one type to another.

What are the types of forces mentioned?

Magnetism, buoyancy, tension, compression, gravity, friction, and centripetal force.

What is net force?

The total or cumulative force acting on an object.

What unit is used to measure force?

Newton (N) is the unit of measurement for force.

What is the formula for speed?

Speed is defined as distance traveled over time.

How is velocity different from speed?

Velocity indicates speed with direction, while speed does not include direction.

What does acceleration measure?

Acceleration measures the change in velocity over time.

What is Newton's First Law of Motion?

An object in motion stays in motion, and an object at rest stays at rest unless acted upon by an external force.

What does the formula F=ma represent?

The force acting on an object is equal to its mass multiplied by its acceleration.

Why does a larger mass require more force to move?

The greater the mass of the object, the more force is required to achieve the same acceleration.

What is inertia?

The resistance of an object to change its state of motion.

What are balanced forces?

Forces that cancel each other out resulting in a net force of zero.

What role does friction play in motion?

Friction resists motion and can cause an object to slow down or stop.
