▪ Displacement - AnsThe distance traveled in a particular direction - it is a vector with magnitude and direction. ▪ Instantaneous Speed - AnsThe rate of change of distance at a specific moment in time - change in distance divided by an infinitesimal interval of time. ▪ Average Speed - AnsThe rate of change of distance calculated over a complete journey ▪ Velocity - AnsA vector quantity equal to the rate of change of displacement. ▪ Average Velocity - AnsThe change in displaceme...

▪ Displacement - AnsThe distance traveled in a particular direction from a fixed origin ▪ Velocity - AnsRate of change of displacement ▪ Acceleration - AnsRate of change of velocity ▪ Newton's First Law - AnsA body will remain at rest or continue to move with constant velocity unless acted upon by a resultant force ▪ Newton's Second Law - AnsThe rate of change of momentum of an object is directly proportional to the resultant force and takes place in the direction of the forc...
