Projectile Motion Quiz

What is a projectile?

• A body moving within a fluid, not in contact with the ground

• A stationary object on the ground

• A body moving in a vacuum

• A body moving only in water

Which factor affects the horizontal distance a projectile will travel?

• Color of the projectile

• Height of release

• Material of the projectile

• Temperature of the air

How does the speed of release affect a projectile?

• It decreases the distance traveled

• It has no effect on the distance

• The greater the speed, the further the distance

• It only affects the vertical distance

What is the optimal angle of release for a projectile if the height of release is the same as landing?

• 30 degrees

• 60 degrees

• 45 degrees

• 90 degrees

Which force acts vertically downwards from the center of mass on a projectile in flight?

• Air resistance (AR)

• Weight (W)

• Friction

• Tension

What factors affect the size of the air resistance (AR) arrow in a free body diagram?

• Mass and gravity

• Velocity, frontal cross-sectional area, streamlining/shape, and surface characteristics

• Temperature and pressure

• Altitude and humidity

What shape is used to show the size and direction of the resultant force?

• Triangle

• Circle

• Parallelogram

• Rectangle

How is the resultant force (R) determined in the parallelogram of forces method?

• By adding the forces directly

• By drawing a diagonal across the parallelogram from the origin of the two forces

• By subtracting the smaller force from the larger force

• By multiplying the forces

What is a parabolic curve?

• A curve that is symmetrical about its highest point.

• A curve that is not symmetrical about its highest point.

• A curve that is always horizontal.

• A curve that is always vertical.

What determines the shape of the flight path of a body?

• The color of the body.

• The relative sizes of weight and air resistance.

• The temperature of the air.

• The speed of sound.
