Acceleration Quiz

What does a constant acceleration imply about an object's motion?

• The object moves at a constant speed.
• The object changes its velocity uniformly over time.
• The object is stationary.
• The object is decelerating.

If an object is accelerating, which of the following statements is always true?

• The object is moving in a straight line.
• The object is increasing its speed.
• The object's velocity is changing.
• The object is experiencing no forces.

Which scenario illustrates negative acceleration?

• A car speeding up on a highway.
• A ball dropped from a height.
• A cyclist slowing down at a stoplight.
• A rocket taking off.

What can be said about an object moving in a circular path at constant speed?

• It has no acceleration.
• Its acceleration points outward.
• Its acceleration is directed towards the center of the circle.
• Its speed is changing.

An object starts with a velocity of 20 m/s and accelerates at 2 m/s² for 5 seconds. What is its final velocity?

• 10 m/s
• 30 m/s
• 40 m/s
• 50 m/s

Which statement about acceleration is accurate?

• Acceleration only occurs when speeding up.
• An object can accelerate while maintaining constant speed.
• Acceleration is always in the direction of motion.
• Acceleration only occurs with opposing forces.

What is the acceleration of an object moving at a constant velocity of 10 m/s?

• 0 m/s²
• 10 m/s²
• Depends on the object's mass.
• Depends on the time of motion.

How is acceleration defined in relation to velocity and time?

• Acceleration is velocity divided by time.
• Acceleration is the change in velocity divided by time.
• Acceleration is the product of velocity and time.
• Acceleration is the change in time divided by velocity.

Which of the following best describes uniform acceleration?

• Acceleration that varies over time.
• Acceleration that is constant in magnitude and direction.
• Acceleration that only occurs when an object is falling.
• Acceleration that results in a change of direction only.

Which of the following scenarios would result in zero acceleration?

• A car moving at a constant speed on a straight road.
• A ball thrown straight up.
• A cyclist speeding up.
• A rocket in free fall.
