Projectile Motion

The path followed by a projectile is also known as its

• trajectory

• range

• height

• vertical displacement

Answer explanation

The path followed by a projectile is called its trajectory.

What is the acceleration of a projectile?

• 0 m/s²

• 9.8 m/s²

Answer explanation

The acceleration of a projectile is 9.8 m/s^2, which is the correct choice.

What is the velocity of a projectile at its highest point?

• 9.8 m/s²

• 9.8 m/s

• 0 m/s²

• 0 m/s

Answer explanation

The velocity of a projectile at its highest point is 0 m/s because it momentarily stops before changing direction.

At what point can we measure the maximum height?

• A

• B

• C

• D

• None of these points

Answer explanation

The maximum height can be measured at point B. It is the highest point reached by the object during its motion.

At which point can we measure the maximum range of the projectile? (it's landing point)

• A

• C

• D

• E

Answer explanation

The maximum range of the projectile, which is its landing point, can be measured at point E. This is the correct choice.

At which point is the velocity of the object the same as the initial velocity at A?

• A

• C

• D

• E

Answer explanation

The velocity of the object is the same as the initial velocity at point E. This is because point E is the correct choice where the velocity remains constant and equal to the initial velocity.

At which point could you measure half the time the projectile is in the air?

• A

• C

• D

• E

Answer explanation

You can measure half the time the projectile is in the air at point C, as it is equidistant from the launch and landing points.

At which point is our object slowing down?

• B

• D

• E

• All points

Answer explanation

The object is slowing down at point B because it experiences a decrease in speed.

At which of the following places does a projectile have the greatest acceleration?

• At the peak of its trajectory

• Half way to the peak

• At the instant it is launched

• All points have the same acceleration

Answer explanation

The projectile has the same acceleration at all points of its trajectory.
