Basic concepts
What is Physics?
The study of matter, energy, motion, and forces.
What formula do we use to calculate speed?
V = d/t
Convert 36 km/h to m/s.
10 m/s.
What does the slope of a velocity-time graph represent?
Acceleration.
Which planet is known as the Red Planet?
Mars
What is the difference between distance and displacement?
Distance is the total path traveled. Displacement is the change in position from start to finish, including direction.
What formula do we use to calculate acceleration?
a = ( vf - vi ) / t
Convert 5 minutes to seconds.
300 seconds.
What happens when an object's velocity decreases?
The object slows down, assuming it continues moving in the same direction.
What is the square root of 144?
12
What is speed?
The distance traveled per unit of time.
How do we calculate the slope of a line?
m = (y2-y1) / (x2-x1)
A student walks 100 meters in 20 seconds. What is the student's speed?
5 m/s.
What is a force?
A push or a pull.
Who wrote Don Quixote?
Miguel de Cervantes.
What is velocity?
Speed in a specific direction.
How many meters are in one kilometer?
1,000 meters.
A car increases its velocity from 5 m/s to 15 m/s in 5 seconds. What is its acceleration?
2 m/s².
What is gravity?
A force of attraction between objects with mass.
What is the largest ocean in the world?
Pacific Ocean.
What is the difference between speed and velocity?
Speed has magnitude only; velocity has magnitude and direction.
How many seconds are in one minute?
60 seconds.
What is the unit of acceleration?
Meters per second squared (m/s²).
What is friction?
A force that opposes relative motion between surfaces in contact.
What is the largest organ in the human body?
The skin.
