Linear Speed

What is Linear Speed?

What is Linear Speed? Linear Speed: The speed of an object traveling along a circular path.

What is Linear Speed? Linear Speed: The speed of an object traveling along a circular path. - May just be along an arc

Recall:

Recall: Linear Speed: Formula:

Recall: Linear Speed: Formula: * θ MUST BE IN RADIANS!!

Example 1: r = 12 m t = 11 sec.

Example 1: r = 12 m t = 11 sec.

Example 1: r = 12 m t = 11 sec. .

Example 1: r = 12 m t = 11 sec. m/sec.

Example 2: r = 42 ft t = 6 min.

Example 2: r = 42 ft t = 6 min.

Example 2: r = 42 ft t = 6 min.

Example 2: r = 42 ft t = 6 min. ft/min.

Example 3: r = 11 mi. t = 1.5 hr.

Example 3: r = 11 mi. t = 1.5 hr.

Example 3: r = 11 mi. t = 1.5 hr.

Example 3: r = 11 mi. t = 1.5 hr.

Example 3: r = 11 mi. t = 1.5 hr.

Example 3: r = 11 mi. t = 1.5 hr. mph

Practice 1: r = 21 m t = 7 sec.

Practice 2: r = 150 ft t = 45 sec.

Practice 3: r = 2 mi. t = 0.5 hr.
