This unit of force in the SI system equals the force needed to accelerate 1 kilogram at 1 meter per second squared.
This property of matter describes its resistance to changes in motion, explaining why heavier objects are harder to push.
This force acts between surfaces in contact and opposes the sliding motion of objects against each other.
This type of energy is stored in an object due to its position or height above the ground.
This type of energy depends on an object's motion and increases with both mass and speed.
This quantity measures how fast an object's position changes over time and includes both speed and direction.
This quantity, measured in Joules, equals force times distance and represents energy transferred when moving an object.
This type of collision conserves both momentum and kinetic energy, like ideal billiard balls striking each other.
