Forces and Motion

A force is a push or pull acting upon an object, resulting from its interaction with another object.

Net force is the total force acting on an object when all the individual forces are combined.

Net force (F_net) = F1 + F2 + ... + Fn, where F1, F2, ..., Fn are the individual forces acting on the object.

The normal force is the support force exerted upon an object that is in contact with a stable surface.

Friction opposes the motion of an object, acting in the opposite direction to the applied force.

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

According to Newton's second law, F = m * a, where F is force, m is mass, and a is acceleration.

Inertia is the tendency of an object to resist changes in its state of motion.

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant velocity.

Unbalanced forces cause an object to accelerate in the direction of the net force.
