One Dimensional Motion

Question 1

Scalars and Vectors

Answer 1

Scalars - only the magnitude (number and unit) of an object

Vectors - describes the magnitude and the direction of an object

Question 2

Displacement vs. Distance

Answer 2

Displacement - the distance from the initial position to the final position. Shortest line that connects its initial and final position points.

Distance - total length covered/travelled

Question 3

Velocity vs. Speed

Answer 3

Velocity - how fast + where it’s going. The way your position changes over time

Speed - how fast an object is moving

Question 4

Time & Acceleration

Answer 4

Time - how long

Acceleration- how fast the velocity is moving. The rate of change of velocity

Question 5

Free Fall

Answer 5

Happens when you either drop a ball or throw a ball straight upwards with no horizontal component.

Gravitational Acceleration = -9.81 m/s^2

Question 6

Projectile Motion

Answer 6

Same as Free Fall but with horizontal component
