MOTION (UAM)
LINEAR MOTION
• object travels in a straight line,
• and its velocity remains
constant
• d = v t
• object is travelling in a
straight line
• with an increase in velocity at
equal intervals of time

9. UNIFORMLY
ACCELERATED MOTION
(UAM)
• When a body moves
exclusively under the influence
of the Earth's gravity, it is said
to be in freefall.
• -9.81 m/s2

10. UNIFORM MOTION
SAMPLE PROBLEM SOLVING
Given:
• s = 65km/hr
• t = 2 hours
• Unknown = d
Solution:
• d = t x s
• d = 2hr x g65 km/hr
Answer
• 130 km
The speed limit in a long, straight highway is 65 km/h. if a bus
moves at this speed for 2 hours, how many km it travels?

11. Example 1: A car that is at rest starts to accelerate 2m/s, if it keeps
accelerating for 10 seconds, define the velocity that the car will reach.

12. UNIFORMLY ACCELERATED MOTION (UAM)
Sample Problem
Example 2: A person that starts walking at a speed of 1m/s start accelerating and 30
seconds later this person is already running at a speed of 5m/s, what was the distance that
this person run?

13. UNIFORMLY ACCELERATED MOTION (UAM)
Sample Problem
Example 3: A car that is going at a speed of 33.2 m/s starts
slowing down and it ends up at rest, if we know that the
acceleration applied was of -2m/s ¿What was the distance that
this car covered?

14. UNIFORMLY ACCELERATED MOTION (UAM)
Sample Problem
Example 4: a light plane is flying at a
velocity of 12m/s, if this accelerates and
it reaches a velocity of 20m/s, and if we
know that between this it covered a 300
meters distance, what was the time and
what was the acceleration.

12m/s, if this accelerates and it reaches a velocity
of 20m/s, and if we know that between this it
