please explain acceleration ???

CAN U PLEASE DIFFRENTIATE BETWEEN DISTANCE A ND DISPLACEMENT PRESENTED IN 2 COLOMNS ???

 in the video it says that distance cannot be zero but in the explanation it says that the minimum value of distance is zero.

1. a body moves from rest with uniform acceleration and travels 270 m in 3 s.find the velocity of the body at 10 s after the start

1. when brakes are applied to a bus the retardation produced is 25 cm s and the bus takes 20 s to stop calculate
2. the initial velocity of bus
3. the distance travelled by bus during this time

1. a car travels with a uniform velocity of 25 m s for 5 s the brakes are then applied and the car is uniformly retarded and comes to rest in further 10 s find
2. the distance which the car travels before the brakes are applied
3. the retardation
4. the distance travelled by the car after applying the brakes

1. a train starts from rest and accelerates uniformly at a rate of 2 m s for 10 s it then maintains a constant speed for 200 s the brakes are then applied and the train is uniformly retarded and comes to rest in 50 s
2. find
3. the maximum velocity reached
4. the retardation in the last 50 s
5. the total distance travelled
6. the average velocity of the train

1. a body falls from the top of a building and reaches the ground 2.5 s later how high is the building?
2. take g =9.8 m s

1. a train starts from rest and accelerates uniformly at a rate of 2 m s for 10 s. it then maintains a constant speed for 200 s the brakes are then applied and the train is uniformly retarded and comes to rest in 50 s find
2. the retardation in the last 50 s
3. the maximum velocity reached
4. the total distance travelled
5. the average velocity of the train

1. a pebble is thrown vertically upwards with a speed of 20 m s how high will it be after 2 s
2. take g =10 m s

a train moving with a velocity of 20 m s is brought to rest by applying brakes in 5 s calculate the retardation

a bullet initially moving with a velocity 20m s strikes a target and comes to rest after penetrating a distance 10 cm in the target calculate the retardation caused by the target

a toy car initially moving with a uniform velocity of 18 km h comes to a stop in 2 s find the retardation of the car in SI units

a bicycle initially moving with a velocity 5.0 m s accelerates for 5 s at a rate of 2 m s what will be its final velocity

a car starting from rest acquires a velocity 180m s in 0.05 h find the acceleration
