If John Cena's speed increases from 15 m/s to 25 m/s over 5 seconds, what is his acceleration?
1 m/s²
2 m/s²
3 m/s²
4 m/s²
How do you calculate acceleration?
a = (final velocity - initial velocity) / time
a = (initial velocity - final velocity) * time
a = final velocity / time
a = initial velocity + final velocity
What does it mean if an object has constant acceleration?
The object's velocity changes at a steady rate over time.
The object's speed remains the same throughout its motion.
The object moves in a straight line without changing direction.
The object's acceleration varies randomly over time.
What is the difference between speed and velocity?
Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
Speed and velocity are the same; both are scalar quantities.
Velocity is a scalar quantity, while speed is a vector quantity.
Speed is measured in meters per second, while velocity is measured in kilometers per hour.
What is the significance of the time variable in acceleration calculations?
Time is crucial in determining how quickly an object's velocity changes, affecting the calculated acceleration.
Time has no effect on acceleration calculations.
Time is only relevant in distance calculations, not acceleration.
Time is used to measure the total distance traveled by an object.
What is acceleration?
Acceleration is the rate of change of velocity of an object.
Acceleration is the force applied to an object.
Acceleration is the distance traveled by an object over time.
Acceleration is the speed of an object in a given direction.
If Nyla slows down from 56 miles/hour to 6 miles/hour in 25 seconds, what is her acceleration?
-2 m/s²
-1 m/s²
0 m/s²
2 m/s²
What is the formula for calculating final velocity?
v = initial velocity + (acceleration × time)
v = initial velocity - (acceleration × time)
v = (initial velocity × time) + acceleration
v = (initial velocity ÷ time) + acceleration
If a car's velocity decreases from 83 m/s to 33 m/s in 4 seconds, what is the acceleration?
-12.5 m/s²
5 m/s²
-10 m/s²
0 m/s²
How can you tell if an object is accelerating from a graph?
If the slope of the velocity-time graph is positive, the object is accelerating; if it's negative, the object is decelerating.
If the graph is a straight line, the object is accelerating.
If the velocity-time graph is horizontal, the object is accelerating.
If the slope of the velocity-time graph is zero, the object is accelerating.
What does a negative acceleration indicate?
The object is speeding up.
The object is moving at a constant speed.
The object is slowing down.
The object is changing direction.
What is the unit of acceleration?
meters per second (m/s)
meters per second squared (m/s²)
kilometers per hour (km/h)
feet per second (ft/s)
What is the acceleration of Billy's car if it slows from 190 m/s to 12 m/s in 20 seconds?
-8.9 m/s²
-5.0 m/s²
-10.5 m/s²
-7.2 m/s²
How do you interpret a positive acceleration?
A positive acceleration means that the object is speeding up.
A positive acceleration means that the object is slowing down.
A positive acceleration means that the object is at rest.
A positive acceleration means that the object is moving in a negative direction.
What is the acceleration of a motorcycle that increases speed from 25 m/s to 55 m/s in 10 seconds?
2 m/s²
3 m/s²
4 m/s²
5 m/s²
