▪ 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...

Velocity - AnsRate of change of displacement Acceleration - AnsRate of change of velocity Scalar quantity - AnsA quantity that has magnitude only and has no direction Vector quantity - AnsA quantity that has both magnitude and direction Thinking distance - AnsThe distance travelled by the vehicle in the time it takes the driver to react Braking distance - AnsThe distance travelled by the vehicle after applying the brakes Stopping distance - AnsThinking distance + braking distance ...

▪ What are the SI base units? - Ans Metre, kilogram, ampere, mole, second, kelvin ▪ Scalar quantity - Ans Has magnitude but no direction ▪ Vector quantity - Ans Has both magnitude and direction ▪ Acceleration - Ans rate of change of velocity ▪ Define the Newton - Ans the force that causes a mass of 1kg to have an acceleration of 1ms^-2 in the direction of the force ▪ Tension - Ans The force within a stretched cable or rope ▪ Normal contact force - Ans The force that arises ...

▪ 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...
