- It is how fast an object is moving.
- Is a vector quantity that indicates distance per time and direction.
- Acceleration is the rate of change of velocity of an object with respect to time. An object’s acceleration is the net result of all forces acting on the object, as described by Newton’s Second Law. The SI unit for acceleration is metre per second squared.
- Displacement is an object’s change in position, only measuring from its starting position to the final position.
Equations of Motion
- Equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.
- Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions).
- A quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude.
- A scalar or scalar quantity in physics is a physical quantity that can be described by a single element of a number field such as a real number, often accompanied by units of measurement. A scalar is usually said to be a physical quantity that only has magnitude and no other characteristics.
- Projectile motion is a form of motion experienced by an object or particle (a projectile) that is thrown near the Earth’s surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible).
