Motion: Projectile Motion

What is projectile motion?

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

• 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 thrown or projected into the air, subject to gravity and air resistance.

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

What are the two components of projectile motion?

• sideways motion and diagonal motion

• forward motion and backward motion

• horizontal motion and vertical motion

• upward motion and downward motion

Explain the horizontal component of projectile motion.

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

• The horizontal component of projectile motion changes direction constantly.

• The horizontal component of projectile motion involves constant motion at a constant horizontal velocity.

• The horizontal component of projectile motion involves acceleration in the horizontal direction.

Explain the vertical component of projectile motion.

• The vertical component of projectile motion remains constant throughout the motion

• The vertical component of projectile motion accelerates upwards

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

• The vertical component of projectile motion is influenced by gravity, resulting in a constant acceleration downwards.

What is the path followed by a projectile in motion?

• Spiral

• Parabola

• Straight line

• Circle

How does air resistance affect projectile motion?

• Air resistance increases the horizontal range of a projectile

• Air resistance has no effect on the maximum height of a projectile

• Air resistance decreases the horizontal range and maximum height of a projectile.

• Air resistance causes a projectile to travel faster

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

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

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

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

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

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

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

• time of flight = (initial velocity * tan(angle of projection)) / acceleration due to gravity

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

• time of flight = (initial velocity * sin(angle of projection)) / 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.

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

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

• Decreasing the angle of projection increases 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 * sin(theta)) / g

• h = (v^2 * cos(theta)) / (2 * g)

• h = (v * sin(theta)) / g
