is speed the same as velocity or acceleration
Velocity Speed describes only how fast an object is moving, whereas velocity gives both how fast it is and in which direction the object is moving.[1] If a car is said to travel at 60 km/h, its speed has been specified. However, if the car is said to move at 60 km/h to the north, its velocity has now been specified.
Inertia Inertia is the resistance of any physical object to any change in its state of motion. This includes changes to the object's speed, direction, or state of rest.
Rate equation k is the first order rate constant, which has units of 1/s or sâˆ’1.
g-force Human tolerances depend on the magnitude of the g-force, the length of time it is applied, the direction it acts, the location of application, and the posture of the body.[7][8]:350
