force and motion

Question 1

What is a scalar quantity?

Answer 1

A measurement that only needs a single number to describe it

Question 2

List four examples of scalar quantities

Answer 2

Mass, time, distance, speed

Question 3

What is a vector quantity?

Answer 3

A measurement that needs both size and direction

Question 4

List three examples of vector quantities

Answer 4

Displacement, velocity, acceleration

Question 5

What’s the difference between speed and velocity?

Answer 5

Speed is just how fast, velocity includes direction of movement

Question 6

What happens to displacement if you return to starting point?

Answer 6

It equals zero, regardless of distance traveled

Question 7

Answer 7

s

Question 8

What are the basic units for measuring displacement?

Answer 8

Meters (m)

Question 9

What units are used to measure velocity?

Answer 9

Meters per second (m/s)

Question 10

What units are used to measure acceleration?

Answer 10

Meters per second squared (m/s²)

Question 11

What does ‘u’ represent in SUVAT equations?

Answer 11

Initial velocity

Question 12

What does ‘v’ represent in SUVAT equations?

Answer 12

Final velocity

Question 13

What does ‘a’ represent in SUVAT equations?

Answer 13

Acceleration

Question 14

What does ‘t’ represent in SUVAT equations?

Answer 14

Time

Question 15

What equation finds final velocity with constant acceleration?

Answer 15

v = u + at

Question 16

How do you calculate displacement using initial velocity and time?

Answer 16

s = ut + (1/2)at²

Question 17

What equation relates velocity and displacement?

Answer 17

v² = u² + 2as

Question 18

How can vector directions be expressed?

Answer 18

Using positive/negative, compass directions, or degrees

Question 19

What’s the main difference between distance and displacement?

Answer 19

Distance is total path length, displacement is straight line from start to end
