What is acceleration?
Click to flip
Acceleration is the rate at which an object changes its velocity.
Click to flip
What units are used to measure acceleration?
Click to flip
Acceleration is commonly measured in meters per second squared (m/sĀ²).
Click to flip
How does acceleration relate to velocity?
Click to flip
Acceleration refers to the change in velocity over time.
Click to flip
Can an object be accelerating if it's moving at a constant speed?
Click to flip
Yes, if the direction of the object is changing.
Click to flip
What is the formula for calculating acceleration?
Click to flip
The formula for acceleration is a = (v_f - v_i) / t.
Click to flip
What is uniform acceleration?
Click to flip
Uniform acceleration occurs when an object's acceleration remains constant over time.
Click to flip
Give an example of acceleration in everyday life.
Click to flip
Accelerating on a highway entrance ramp.
Click to flip
How is deceleration related to acceleration?
Click to flip
Deceleration is negative acceleration, meaning the object slows down.
Click to flip
What is the acceleration due to gravity on Earth?
Click to flip
The acceleration due to gravity is approximately 9.8 m/sĀ².
Click to flip
Is acceleration a scalar or a vector quantity?
Click to flip
Acceleration is a vector quantity.
Click to flip
What happens to the acceleration if the net force is doubled?
Click to flip
The acceleration doubles, assuming mass remains constant.
Click to flip
What role does friction play in acceleration?
Click to flip
Friction opposes motion and can decrease acceleration.
Click to flip
How is acceleration depicted on a velocity-time graph?
Click to flip
It is shown as the slope of the line on a velocity-time graph.
Click to flip
What effect does mass have on acceleration?
Click to flip
More mass decreases acceleration when the force is constant.
Click to flip
Can acceleration occur in three dimensions?
Click to flip
Yes, acceleration can occur in three dimensions if the object's velocity changes in any spatial direction.
