• An object at rest

• A car traveling on a highway without changing lanes

• An object moving at a constant speed in a straight line

• A book lying on a table

• An object changing direction while moving at a constant speed

Organize these physical quantities into vector and scalar quantities.

Groups:

(a) Vector

,

(b) Scalar

• Speed

• Acceleration

• Distance

• Velocity

• Displacement

Which of the following statements are FALSE?

• If an object has a negative velocity it is going slowly

• If an object has a negative acceleration it is speeding up

• If an object has a positive acceleration the is speeding up

• The acceleration of an object depends on the direction of the velocity

Categorize the following scenarios for an object.

Groups:

(a) Speeding Up

,

(b) Slowning Down

,

(c) Constant Velocity

• v = 25 mph, a = -3 mph^2

• v = 5 m/s, a = 0.5 m/s^2

• v = -8 m/s, a = 0.2 m/s^2

• v = 13.5 m/s, a = 0 m/s^2

• v = -10.2 mph, a = 0 m/s^2

• v = -30 mph, a = -2 mph^2
