Projectile Motion Intro

What is projectile motion?

• Motion along a straight path
  

• Motion of an object thrown into the air, influenced only by gravity and air resistance

• Motion in a vacuum with no forces acting on it

• Motion that only moves in a horizontal direction

Which of the following is NOT a factor affecting projectile motion?

• Initial velocity

• Mass of the object

• Angle of projection 

• Gravity

A soccer ball is kicked at 25 m/s at an angle of 40°. What is its horizontal velocity component?

• 16.07 m/s

• 19.15 m/s 

• 23.5 m/s

• 30 m/s

What is the shape of the trajectory of a projectile?

• Circular

• Parabolic 

• Linear

• Elliptical

A basketball player shoots a ball at an angle of 45°. What will happen to the range if the angle is increased to 60° (assuming the same initial velocity)?

• The range will increase 

• The range will decrease

• The range will stay the same

• The range will double
