Describing and Measuring Motion

Describing and Measuring Motion

By Flora Heyrosa

Open Ended

It refers to the process of an object moving or being moved.

Open Ended

It is the background or object that is used for comparison that something is moving.

Examine the illustration above. How would you know that the car is moving?

​Some text here about the topic of discussion.

Poll

What type of motion is shown in the given illustration?

(A coconut falling from a tree.)

• Linear Motion

• Curvilinear Motion

Poll

What type of motion is shown in the given illustration?

(A group of young adults riding a roller coaster.)

• Linear Motion

• Curvilinear Motion

Open Ended

What do you call the length of the path between two points?

Multiple Choice

What is the basic unit of length in the International System of Units?

• meter

• inch

• foot

• yard

Open Ended

What is:

a. 1 kilometer to meter

b. 1 meter to centimeter

c. 1 centimeter to millimeters

Open Ended

Convert 5 km to m.

Multiple Choice

Which statement is false?

• Speed refers to "how fast an object is moving."

• A stopwatch is used to measure accurate time in minutes, seconds, and milliseconds.

• Motion is the length of the path between two points.

• Speed increases as time decreases, and speed decreases as time increases.

Suppose a mountain bike racer finishes a 120 m race in 10 s. What is the racer's average speed? (i..e, the distance covered by an object divided by the time it takes to travel that distance)

Solve.

S = d/t

Speed Equation

Measuring Speed

Constant speed means that speed is not increasing or decreasing but remain consistent over time. If velocity is zero, the acceleration is also zero.

Definition

Constant Speed

Maria runs at an average speed of 5 kph. If she runs for 2 hours, how far does she travel?

Solve.

D = s x t

Distance Equation

Measuring Distance

Acceleration is the measurement of change in an object's velocity. When you press down on the gas pedal in a car, the car surges forward going faster and faster. This change in velocity is acceleration.

If you get the speed of an object plus its direction, you get the VELOCITY.

10 km/h, East​
