Distance, Displacement, Speed And Velocity

Question 1

What is distance?

Answer 1

How far an object has moved and it’s scalar.

Question 2

What is displacement?

Answer 2

Vector and measures distance and direction of a straight line from start to finish point.

Question 3

What is speed?

Answer 3

How fast you’re going

Question 4

What is velocity?

Answer 4

Speed in a given direction.

Question 5

What is the equation for distance traveled?

Answer 5

Distance travelled(m)= speed (m/s) x time (s)

Question 6

What is the equation for acceleration?

Answer 6

Acceleration(m/s2)=

change in velocity
___________________________
Time (s)

Question 7

What is the equation for uniform acceleration?

Answer 7

Final velocity-initial velocity= 2x acceleration x distance

Question 8

What does gradient mean on a distance time graph?

Answer 8

Speed

Question 9

What is gradient on a velocity time graph?

Answer 9

Acceleration

Question 10

What can reduce drag?

Answer 10

Keeping the object streamlined.

Question 11

What increases as speed decreases?

Answer 11

Drag

Question 12

What is terminal velocity?

Answer 12

Objects fall and gravity is more than friction so they accelerate.
Speed increases so friction builds up.
This reduces acceleration.
