AP Physics 1 Kinematics Quiz

What is the main difference between a vector and a scalar quantity?

• Vectors have both magnitude and direction.

• Vectors have only magnitude.

• Scalars have both magnitude and direction.

• Scalars have only direction.

When adding vectors, what method should be used?

• Add them from head to head.

• Add them from tail to head.

• Add them from head to tail.

• Add them from tail to tail.

How is displacement different from distance?

• Displacement and distance are the same.

• Displacement is the shortest path between two points, while distance is the total path traveled.

• Displacement is the total path traveled, while distance is the shortest path.

• Displacement is a scalar, while distance is a vector.

What does the slope of a velocity vs. time graph represent?

• Displacement

• Speed

• Acceleration

• Time

Which kinematic equation is not typically found on a reference table?

• v = u + at

• s = ut + 0.5at^2

• v^2 = u^2 + 2as

• s = vt - 0.5at^2

What is the acceleration due to gravity on Earth?

In free fall, what happens to the velocity of an object at its apex?

• It is at its maximum.

• It is zero.

• It is constant.

• It is negative.

What is the initial acceleration in the X direction for a horizontal projectile?

• Equal to the Y direction acceleration

• Depends on the initial velocity

• 0 m/s^2

• 9.8 m/s^2

How does increasing the initial velocity in the X direction affect the flight time of a projectile?

• It increases the flight time.

• It does not affect the flight time.

• It decreases the flight time.

• It doubles the flight time.

What links the X and Y directions in projectile motion analysis?

• Displacement

• Acceleration

• Velocity

• Time
