8.4 (Term 1) Flashcards
Glossary: Acceleration Deceleration Gravity Objectives: The definition for acceleration and deceleration and difference between acceleration and deceleration. Formula for acceleration. SI units for acceleration Describe why there is acceleration due to gravity and recall that g = 9.8 m/s2 downwards
What is acceleration a measure of?
Acceleration is a measure of the rate at which velocity changes.
How can average acceleration be calculated?
Average acceleration is calculated by dividing the change in velocity by the time taken for the change.
What is the SI unit for acceleration?
The SI unit for acceleration is meters per second squared (m/s²).
What does a positive value for acceleration indicate?
A positive value for acceleration indicates speeding up.
What does a negative value for acceleration indicate?
A negative value for acceleration indicates slowing down.
What is another term for slowing down?
Slowing down is also called deceleration.
What is the acceleration due to gravity near the surface of the Earth?
The acceleration due to gravity near the surface of the Earth is 9.8 m/s².
