What is the only force assumed to act on a projectile in this simulation?

• Friction

• Air resistance

• Magnetic force

• Gravity

Why is the motion broken into x and y components in the simulation?

• To simplify calculations

• Because there are forces in both directions

• To separate horizontal and vertical forces

• To account for air resistance

What happens to the velocity in the x direction during the projectile's journey?

• It fluctuates

• It remains constant

• It decreases

• It increases

At what point is the velocity in the y direction zero?

• At launch

• At peak height

• At impact

• At the start

• 100 km/h

• 72 km/h

• 20 km/h

• 50 km/h

How is the initial velocity in the y direction determined for the cannonball?

• By calculating the height

• By using the speed formula

• By observing the vector direction

• By measuring the angle

What is the time of flight for the cannonball before it hits the ground?

• 2.5 seconds

• 1.5 seconds

• 3.194 seconds

• 5 seconds

What formula is used to calculate the distance traveled by the cannonball?

• Distance = Time / Speed

• Speed = Distance / Time

• Distance = Speed / Time
