Motion Challenge

What is projectile motion?

• Projectile motion is the motion of an object moving in a straight line without any external forces.

• Projectile motion is the motion of an object following a circular path due to centrifugal force.

• Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. It follows a curved path known as a parabola.

• Projectile motion is the motion of an object that defies the laws of gravity.

Explain the difference between horizontal and vertical components of projectile motion.

• The horizontal component of projectile motion is influenced by gravity, while the vertical component is constant.

• The horizontal component of projectile motion is constant and unaffected by gravity, while the vertical component is influenced by gravity and changes over time.

• Both the horizontal and vertical components of projectile motion are constant and unaffected by gravity.

• The horizontal component of projectile motion changes over time, while the vertical component is constant.

How does air resistance affect projectile motion?

• Air resistance slows down the projectile, reducing its horizontal range and maximum height.

• Air resistance causes the projectile to move in a straight line

• Air resistance increases the speed of the projectile

• Air resistance has no effect on projectile motion

Calculate the maximum height reached by a projectile launched at an angle of 30 degrees with an initial velocity of 20 m/s.

• 10.2 meters

• 8.9 meters

• 15.7 meters

• 12.4 meters

Derive the equation for the range of a projectile launched at an angle θ with an initial velocity v.

• R = (v^2 * tan(θ)) / g

• R = (v^2 * cos(2θ)) / g

• R = (v^2 * sin(θ)) / g

• R = (v^2 * sin(2θ)) / g
