15 Questions
What did Galileo Galilei discover about the movement of objects down inclined planes?
The velocity of the ball changed because the speed of the ball was changing
What is the concept of inertia?
An object's tendency to resist change in its state of motion
What did Galileo's experiments with inclined planes demonstrate?
The rate of change of velocity, known as acceleration
How did Galileo support his scientific conclusions?
By diligent use of experiments
What describes acceleration?
The change in velocity over time
What was one of the reasons for Galileo's success as a scientist?
His diligent use of experiments
What is the difference between speed and velocity?
Velocity includes direction, while speed does not
What is the formula for acceleration?
a = ΔV/Δt
If a car steadily increases its velocity from 20 km/h to 60 km/h in 3 seconds, what is its acceleration?
13.3 km/h*s
What is the acceleration of an object in free fall when air resistance is negligible?
9.8 m/s2
When a car decelerates, it means that the car's:
Velocity decreases
