Understanding Acceleration and Its Applications

What is acceleration defined as in physics?

• The change in velocity over time

• The change in distance over time

• The change in direction over time

• The change in speed over time

In the context of acceleration, what does a vector quantity mean?

• It has only direction

• It is a constant value

• It has both magnitude and direction

• It has only magnitude

How do you calculate acceleration if a cyclist increases velocity from rest to 4.5 m/s in 5 seconds?

• 0.9 m/s²

• 1.1 m/s²

• 1.0 m/s²

• 0.8 m/s²

What is the simplified form of the acceleration formula when initial velocity is zero?

• V = at

• V = a + t

• V = at + V₀

• V = a - t

How can you solve for time using the acceleration formula?

• t = a * Δv

• t = Δv / a

• t = a / Δv

• t = Δv - a

What does a negative acceleration indicate?

• A decrease in speed

• A change in direction

• An increase in speed

• A constant speed

If a cyclist decelerates from 7.5 m/s to a stop with an acceleration of -2.5 m/s², how long does it take?

• 2 seconds

• 5 seconds

• 3 seconds

• 4 seconds

What happens to the units when calculating acceleration as meters per second squared?

• Seconds cancel out

• Meters cancel out

• Meters per second squared remains

• Seconds squared remains
