Projectile Motion G9

What is the horizontal motion of a projectile?

• Constant and uniform

• Circular and elliptical

• Upward and downward

• Variable and non-uniform

Explain the vertical motion of a projectile.

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

• The vertical motion of a projectile is constant throughout its trajectory

• The vertical motion of a projectile is influenced by gravity, causing the projectile to accelerate downwards at a rate of 9.81 m/s^2.

• The vertical motion of a projectile is influenced by wind resistance

How does the angle of release affect the height of a projectile?

• The angle of release affects the height of a projectile by changing the vertical component of the initial velocity.

• The angle of release affects the height of a projectile by altering the gravitational constant.

• The angle of release affects the height of a projectile by changing the color of the projectile.

• The angle of release affects the height of a projectile by increasing the density of the air.

Describe the relationship between the angle of release and the range of a projectile.

• The range of a projectile is maximum when the angle of release is 90 degrees.

• The range of a projectile is not affected by the angle of release.

• The range of a projectile is minimum when the angle of release is 0 degrees.

• The range of a projectile is maximum when the angle of release is 45 degrees.

Define projectile motion.

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

• Projectile motion is the motion of an object moving in a circular path

• Projectile motion is the motion of an object in a straight line

• Projectile motion is the motion of an object with no external forces acting on it

What is the key characteristic of horizontal motion in projectile motion?

• Variable velocity

• Upward acceleration

• Circular motion

• Constant velocity

In vertical motion of a projectile, what is the effect of gravity?

• Gravity decelerates the projectile upwards.

• Gravity has no effect on the projectile.

• Gravity accelerates the projectile downwards.

• Gravity causes the projectile to move horizontally.

How does the angle of release impact the maximum height reached by a projectile?

• The angle of release impacts the maximum height reached by a projectile by influencing the mass of the projectile.

• The angle of release impacts the maximum height reached by a projectile by altering the air resistance experienced.

• The angle of release impacts the maximum height reached by a projectile by affecting the vertical component of the initial velocity.

• The angle of release impacts the maximum height reached by a projectile by changing the gravitational constant.

Explain the concept of time of flight in projectile motion.

• Time of flight is the time taken for a projectile to reach its maximum speed

• Time of flight is the time taken for a projectile to return to its initial position

• Time of flight is the time taken for a projectile to reach its maximum height

• Time of flight in projectile motion is the total time taken by a projectile to complete its trajectory from launch to landing.

What is the formula for calculating the range of a projectile?

• R = (v^2 * cos(2θ)) / g

• R = (v * sin(θ)) / g

• R = (v^2 * sin(2θ)) / g

• R = (v^2 * sin(θ)) / g
