Motion

Answer

Distance is the total path length covered by an object (scalar quantity). Displacement is the shortest distance between initial and final positions in a specific direction (vector quantity). Distance

Answer

Uniform motion is when an object covers equal distances in equal intervals of time. The speed remains constant. Example: A car moving at a constant speed of 60 km/h on a straight highway, covering 60

Answer

Non-uniform motion occurs when an object covers unequal distances in equal intervals of time. The speed varies. Example: A car moving through city traffic - sometimes fast on clear roads, sometimes sl

Answer

Speed is the rate of motion of an object, defined as distance traveled per unit time. It is a scalar quantity. Formula: Speed = Distance/Time or v = s/t. SI unit: m/s or ms⁻¹

Answer

Velocity is the speed of an object in a specific direction. It is a vector quantity. Difference: Speed has only magnitude (scalar), while velocity has both magnitude and direction (vector). Velocity c

Answer

Given: Distance = 150 km, Time = 3 hours Average speed = Total distance/Total time Average speed = 150 km/3 h = 50 km/h Therefore, the average speed is 50 km/h.

Answer

Acceleration is the rate of change of velocity. It measures how quickly velocity changes with time. Formula: a = (v-u)/t, where v = final velocity, u = initial velocity, t = time. SI unit: m/s² or ms⁻

Answer

Uniform acceleration occurs when velocity changes by equal amounts in equal intervals of time. The acceleration remains constant. Example: A freely falling object under gravity experiences uniform acc
