Projectile Motion

What is projectile motion?

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

• Projectile motion is the motion of an object moving in a circular path due to centripetal force.

• Projectile motion is the motion of an object moving at a constant velocity in a vacuum.

• Projectile motion is the motion of an object thrown or projected into the air, subject to gravity and air resistance.

What are the two components of projectile motion?

• Horizontal motion and vertical motion

• Leftward motion and rightward motion

• Forward motion and backward motion

• Upward motion and downward motion

Explain the horizontal component of projectile motion.

• The horizontal component of projectile motion is always greater than the vertical component.

• The horizontal component of projectile motion is characterized by a constant velocity.

• The horizontal component of projectile motion is affected by air resistance.

• The horizontal component of projectile motion changes over time.

Explain the vertical component of projectile motion.

• The vertical component of projectile motion is the motion of the object in the horizontal direction.

• The vertical component of projectile motion is the motion of the object in the vertical direction, influenced by gravity.

• The vertical component of projectile motion is not affected by gravity.

• The vertical component of projectile motion is constant throughout the motion.

What is the formula to calculate the horizontal distance traveled by a projectile?

• horizontal distance = initial velocity * time * cosine(angle)

• horizontal distance = initial velocity * time * secant(angle)

• horizontal distance = initial velocity * time * tangent(angle)

• horizontal distance = initial velocity * time * sine(angle)

What is the formula to calculate the time of flight of a projectile?

• time = (initial velocity * sin(angle)) * acceleration due to gravity

• time = (initial velocity * sin(angle)) / acceleration due to gravity

• time = 2 * (initial velocity * cos(angle)) / acceleration due to gravity

• time = 2 * (initial velocity * sin(angle)) / acceleration due to gravity

How does the angle of projection affect the range of a projectile?

• The angle of projection affects the range of a projectile by changing the vertical and horizontal components of the initial velocity.

• Decreasing the angle of projection increases the range of a projectile.

• Increasing the angle of projection decreases the range of a projectile.

• The angle of projection has no impact on the range of a projectile.

What is the maximum height reached by a projectile?

• h = (v^2 * sin^2(theta)) / (2 * g)

• h = (v^2 * cos^2(theta)) / (2 * g)

• h = (v^2 * sin(theta)) / g

• h = (v * sin(theta)) / g

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

• Zero

• Decreasing

• Constant

• Increasing

What is the relationship between the horizontal and vertical components of velocity in projectile motion?

• The horizontal component of velocity changes, and the vertical component is constant.

• The horizontal and vertical components of velocity are independent of each other.

• The horizontal component of velocity is constant, and the vertical component changes due to gravity.

• The horizontal component of velocity is greater than the vertical component.
