GENERAL PHYSICS 1

Units and Physical Quantities and Vectors

100

Any numbers used to describe a physical phenomenon quantitatively through direct measurement or derived calculations based on direct measurement

PHYSICAL QUANTITIES

200

Refers to the how far the measured value to a standard or known/true value.

ACCURACY

300

Errors with unexplainable origins or unknown sources affecting the precision of the data

RANDOM ERROR

400

What is the scientific notation of 0.06589?

6.589× 10^-2 

500

The period of oscillation of a simple pendulum in the experiment is recorded as 2.63s. The standard oscillation is found to be at 2.60s. What is the measurement error? average absolute error is:

[2.60-2.63]/2.60 x 100 = 1.15%

Motion, Acceleration and Freefall

100

What is the constant acceleration due to gravity?

9.8 m/s²

200

It happens when a car travels equal distances at equal time intervals; the car is moving at constant speed.

UNIFORM MOTION

300

What is the final velocity of an object thrown upward at its maximum height?

0 m/s

400

A car accelerates from rest to a speed of 36 km/h in 20 seconds. What is the acceleration of the car in m/s²?

[10m/s-0m/s]/[20s-0s]=0.5 m/s²

^{36 km = 36,000 m}

^{1 hr = 3600 s}

^{36 km/hr = 10 m/s}

500

A researcher tests the acceleration due to gravity by dropping a pebble in an evacuated tube. What is the final distance covered by the pebble after 0.5 seconds?

1.225 meters or 1.2 meters

Relative Motion, Projectile Motion and Circular Motion

100

Refers to a linear motion with approximately constant acceleration that has vertical motion of objects thrown into the air or of objects falling through air

Free Fall

200

It is when an object moves in both x and y directions simultaneously, and therefore is considered to be a motion in two dimension.

Projectile Motion

300

The path covered by a projectile

TRAJECTORY

400

Describe the magnitude of the velocity in the horizontal component of a projectile

ALWAYS CONSTANT

500

Describe the magnitude of the acceleration in the horizontal component of a projectile

0 m/s²

Vector and Forces

100

It is the force acting on the earth  which pulls a dropped object toward it.

GRAVITATIONAL FORCE

200

The pulling force exerted by a stretched rope or cord on an object to which it’s attached.

TENSION FORCE

300

What is the NET FORCE acting on a glass of water resting on a table?

ZERO (0)

400

Identify the forces acting on a car by a tow truck.

NORMAL, GRAVITATIONAL/WEIGHT, FRICTIONAL, APPLIED FORCE

500

What is the resultant net force acting on two forces F_x and F_y at right angle with each other?

𝚺𝑭 =SQRT (𝚺𝑭x)² +(𝚺𝑭y)²
