Answer:
Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time.
Explanation:
Put another way, speed is a scalar value, while velocity is a vector. For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.
Verified answer
Answer:
Speed is simply how fast you are travelling
ex. The car is travelling at a speed of 30m/s.
Velocity is speed in a given direction
ex. The car is travelling at a speed of 30m/s east.
Acceleration is the rate of change of velocity
ex. Caleb was walking south at 3 kilometers per hour. Caleb slows down. After, Caleb walks south at 1.5 kilometers per hour. Caleb has had a nonzero acceleration.
