Understanding Projectile Motion

What is the only force acting on a projectile in motion?

• Magnetic force

• Air resistance

• Gravity

• Friction

How do the horizontal and vertical components of a projectile's motion interact?

• They are dependent on each other

• They affect each other slightly

• They are completely independent

• They cancel each other out

In the simulation, what was observed about the time it takes for a projectile to fall vertically?

• It varies randomly

• It remains constant regardless of horizontal speed

• It increases with increased horizontal speed

• It decreases with increased horizontal speed

What does the animation of a ball launched from a moving truck demonstrate?

• The ball's vertical motion affects its horizontal motion

• The ball's horizontal motion affects its vertical motion

• The ball's horizontal and vertical motions are independent

• The ball's motion is unpredictable

What is the role of gravity in the motion of a projectile?

• It only affects vertical motion

• It has no effect on the motion

• It affects both horizontal and vertical motion

• It only affects horizontal motion

According to Newton's first law, what happens to a projectile's horizontal motion in the absence of horizontal forces?

• It accelerates

• It remains constant

• It stops

• It decelerates

What shape does the path of a projectile take when both gravity and horizontal motion are considered?

• Parabolic

• Circular

• Elliptical

• Linear

What is the vertical acceleration of a projectile due to gravity?

• 9.8 m/s² downwards

• 9.8 m/s² upwards

• Varies with speed

• 0 m/s²

What is suggested as a next step to reinforce learning about projectile motion?

• Reading a textbook

• Ignoring the topic

• Watching more videos

• Experimenting with simulations

What is the main takeaway about the motion of projectiles?

• They are affected by multiple forces

• Their motion is unpredictable

• They only move vertically

• Their horizontal and vertical motions are independent
