Review of the past lesson
Yesterday, we discussed UAM, kindly give us a summary of what we discussed at the last meeting.
Again, What is UAM? How about acceleration?
“Very good. You really listened to our discussion last meeting”
Engage (5 mins)
Motivation
“If you want to determine how far a passing vehicle would travel in a given amount of time, how will
you do it?”
“The best way to solve a problem is usually determined by the information that is available to you.”
“Our topic for today is Equations for Uniformly Accelerated Motion”
Presenting the Topic: EQUATIONS OF UNIFORMLY ACCELERATED MOTION
Presenting the objectives:
1. Solve problems related to motion with uniform acceleration in the horizontal dimension
Unlocking Difficult Terms
1. Velocity- is the quickness of motion or action, refers to the measurement of the rate and direction of
change in position of an object. It is a vector quantity that specifies both the speed of a body and its
direction of motion.
2. Speed- Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be
thought of as the rate at which an object covers distance.
3. Distance- Distance is a scalar quantity that refers to "how much ground an object has covered"
during its motion.
4. Displacement- Displacement is a vector quantity that refers to "how far out of place an object is";
it is the object's overall change in position.
5. Acceleration due to gravity- It is known as the acceleration of gravity - the acceleration for any
object moving under the sole influence of gravity.

Explain (20 mins)
Uniformly Accelerated Motion
- The simplest kind of accelerated motion is straight-line motion with constant acceleration. In this
case, the velocity changes at the same rate throughout the motion. Uniformly Accelerated Motion
occurs when a velocity increases by exactly the same amount during each interval.
- UAM has 2 dimensions, the Horizontal and Vertical Dimensions.
“To be able to solve problems related to motion with uniform acceleration, in which the velocity may
change but the acceleration is constant, we need to derive algebraic equations that describe this type of
motion.”
There are 3 equations that are involved in deriving to come up with UAM formulae
1. Velocity
2. Average Velocity
3. Average Acceleration

1. From rest a car accelerated at 8m/𝑠 for 10 s.
a. What is the position of the car at the end of 10 seconds?
b. What is the velocity of the car at the end of 10 seconds?
Therefore, the position of the car at the end of 10 s is 400 meters, and the velocity of the car is 80
m/s.
2. An airplane from rest accelerates on a runway at 5.50 m/s for 20.25s until it finally takes off the
ground. What is the distance covered before takeoff?
Elaborate (10 mins)
The teacher will ask the following questions:
1. What is UAM?
Answer: The simplest kind of accelerated motion is straight-line motion with constant acceleration.
2. What are 3 equations that are involved in deriving to come up with UAM formulae?
Answer:
II. Velocity
III. Average Velocity
IV. Average Acceleration

3. “What equation you may use in problems that do not directly involve displacement but rather
velocity.”
Answer: Equations 1 and 4.
4. “What equation will allow you to determine the displacement?
Answer: Equations 2 and 3

1. A sports car approaches a highway on-ramp at a velocity of 20.0 m/s East. If the car accelerates
at a rate of 3.2 m/s2 East for 5.0 s, what is the displacement of the car?
2. A sailboat accelerates uniformly from 6.0 m/s North to 8.0 m/s North at a rate of 0.50 m/s2
North. What distance does the boat travel?

(b) How far does the dart penetrate into the backstop?
