TEKS 5.D Projectile Motion Intro

When the only force on an object is gravity:

• free fall

• acceleration

• gravity

• range

An object in free fall is also called

• gravity

• projectile motion

• projectile

• tide

Objects will accelerate towards Earth at a rate of

• 1.6 m/s²

• 9.8 m/s²

• 9.8 N

• 1.6 N

What is the direction of the acceleration for any projectile?

• The direction the projectile is traveling.

• Down

• Up

• Sideways

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

Which of the following would NOT be considered a projectile? 

• a cannonball thrown straight up
• a cannon ball rolling down a slope
• a cannonball rolling off a table
• a cannonball thrown in the air

What is the shape of the trajectory followed by a projectile in motion?

• ellipse

• square

• parabola

• circle

What is the acceleration acting on a projectile in the vertical direction?

• 5.67 m/s^2 upward

• 0 m/s^2

• 3.14 m/s^2 downward

• 9.81 m/s^2 downward

Describe the shape of the trajectory of a projectile in motion.

• Parabola

• Spiral

• Hexagon

• Circle

What type of graph is used to represent the horizontal motion of a projectile?

• Pie chart

• Scatter plot
