VELOCITY AND ACCELERATION

Question 1

WHAT DOES SPEED AND VELOCITY HAVE IN COMMON

Answer 1

THEY BOTH SAY HOW FAST YOU ARE GOING AND BOTH ARE MEASURED IN M/S (OR KM/H OR MPH)

Question 2

WHAT IS THE DIFFERENCE BERTWEEN SPEED AND VELOCITY

Answer 2

SPPED IS JUST HOW FAST YOU ARE GOING (30 mph) WITH NO DIRECTION WHILE VELOCITY NEEDS TO SPECIFIY THE DIRECTION AND THE VELOCITY (30mph north or 20mph m/s 060°)

Question 3

WHAT DOES IT MEAN TO HAVE OBJECTS TRAVELLING AT A CONSTANT SPEED WOITH A CHANGING VELOCITY

Answer 3

THAT THE OBJECT IS CHANGING DIRECTION WHILST STAYING AT THE SAME SPEED

Question 4

WHAT IS THE FORMULA FOR ANY OBJECT RELATED WITH MOVEMENT, SPEED AND TIME TAKEN

Answer 4

AVERAGE DISTANCE= DISTANCE MOVED:TIME TAKEN

S
“V” X “T”

Question 5

WHAT IS ACCELERATION

Answer 5

HOW QUICKLY THE VELOCITY IS CHANGING

IT CAN BE A CHAN GE IN SPEED A CHANGE IN DIRECTION OR BOTH

Question 6

WHAT IS THE UNIT OF ACCELERATION

Answer 6

IT IS m/s 2 (squared)

Question 7

WHAT IS THE FORMULAS FOR ACCELERATION AT A CONSTANT SPEED

Answer 7

ACCELERATION= CHANGE IN VELOCITY:TIME TAKEN

Question 8

WHAT IS THE OTHER FORMULA FOR ACCELERATION AT A CONSTANT SPEED

Answer 8

(V-U) : “a” x “t”

V= final velocity
U= initial velocity

Question 9

WHAT DOES A NEGATIVE VALUE FOR ACCELERATION MEAN

Answer 9

THAT IT IS DECELERATING

Question 10

WHAT CHANGES CAN ACCELERATION MAKE

Answer 10

CHANGE IN SPEED AND CHANGE IN DIRECTION OR BOTH
