Picture Analysis: Look at Picture A (a crowded jeepney moving on a city street) and Picture B (a carabao pulling a cart while running in a field). What do you mainly observe happening in these two scenes regarding motion?

• Both objects are at rest the entire time

• Both objects are moving and their speeds are changing

• Only the jeepney is moving while the carabao is stopped

• Only the carabao is moving while the jeepney is stopped

Picture Analysis: Based on Picture A (jeepney with many passengers) and Picture B (running carabao with a cart), what is most likely happening to the speed of the objects?

• Their speeds remain constant

• Their speeds are changing over time

• They instantly stop and never move again

• They only turn without changing speed

Picture Analysis: What is a plausible cause of the change in speed for the jeepney and the carabao shown in the pictures?

• Changes in load or applied force acting on them

• The color of the vehicles and animals

• The day of the week they are moving

• Whether the road is straight or curved only

Guide question: Which situation is an example of an object accelerating?

• A car moving at a constant 50 km/h on a straight, empty highway

• An apple falling from a tree and speeding up as it falls

• A parked bicycle leaning on a wall

• A rock sitting still on the ground

Problem-solving: A jeepney changes its velocity from 17 m/s to 23 m/s in 5 s. What is the acceleration during this interval?

• 0.6 m/s²

• 1.2 m/s²

• 3.0 m/s²

• 6.0 m/s²

Problem-solving: A car accelerates at 3.0 m/s². If its initial velocity is 8.0 m/s, how many seconds are needed to reach a final velocity of 25.0 m/s?

• 2.83 s

• 5.67 s

• 8.33 s

• 11.0 s

• 10 m/s

• 20 m/s

• 25 m/s

• 30 m/s

A student was walking at a speed of 2 m/s when a dog started chasing him. In a panic, he sprinted as fast as he could, reaching a speed of 7 m/s over a 4-second interval. What was his acceleration during that time interval?

• 0.5 m/s^2

• 1.0 m/s^2

• 1.25 m/s^2

• 2.5 m/s^2

A tricycle is moving at 8 m/s. It decelerates and comes to a stop in 5 seconds. Calculate the acceleration of the tricycle.

• -0.8 m/s^2

• -1.6 m/s^2

• -2.0 m/s^2

• -3.2 m/s^2

• 2 s

• 3 s

• 4 s

• 6 s
