Motion Madness

What is the formula to calculate acceleration?

• acceleration = (final velocity + initial velocity) / time

• acceleration = (final velocity - initial velocity) / time

• acceleration = (final velocity - initial velocity) * time

• acceleration = (final velocity * initial velocity) / time

If an object is moving with a constant speed, what can we say about its acceleration?

• The acceleration is increasing

• The acceleration is constant

• The acceleration is zero.

• The acceleration is decreasing

A car accelerates from 20 m/s to 50 m/s in 5 seconds. What is its acceleration?

• 25 m/s^2

• 10 m/s^2

• 15 m/s^2

• 6 m/s^2

How is acceleration related to velocity?

• Acceleration is the derivative of velocity.

• Acceleration is equal to velocity squared.

• Acceleration is the integral of velocity.

• Acceleration is inversely proportional to velocity.

What are the units of acceleration?

• kg

• m/s^2

• km/h

• m

• cm/s

Explain the difference between positive and negative acceleration.

• Positive acceleration results in slowing down, while negative acceleration results in speeding up.

• Positive acceleration results in maintaining speed, while negative acceleration results in stopping.

• Positive acceleration results in speeding up, while negative acceleration results in slowing down.

• Positive acceleration results in decelerating, while negative acceleration results in accelerating.

A train slows down from 30 m/s to 10 m/s in 10 seconds. What is its acceleration?

• 15 m/s^2

• -2 m/s^2

• 0 m/s^2

• 5 m/s^2

How does acceleration affect an object's motion?

• Acceleration always causes an object to move in a straight line

• Acceleration changes an object's velocity over time, either speeding it up, slowing it down, or changing its direction.

• Acceleration only affects the object's color

• Acceleration has no effect on an object's motion

What is the acceleration of an object moving at a constant speed?

• 0

• 2 m/s^2

• 9.8 m/s^2

• 5 m/s^2

Why is acceleration important in the study of motion?

• Acceleration helps quantify changes in velocity and provides insights into the dynamics of motion.

• Acceleration is not a measurable quantity

• Acceleration has no impact on the study of motion

• Acceleration is only relevant in certain situations
