Vertical Projectile Motion Quiz

What is the primary force acting on a projectile in vertical motion?

• Friction

• Magnetic force

• Air resistance

• Gravity

Why is air resistance often ignored in grade 12 physics problems?

• It is not present in real life

• It is too complex to calculate

• To simplify calculations while still understanding basic motion

• It has no effect on motion

Which of the following is a condition for using the equations of motion?

• Variable acceleration

• Motion in a curved path

• Constant acceleration

• Presence of multiple forces

What is the value of acceleration due to gravity on Earth?

• 9.8 m/s²

• 0 m/s²

• 1.4 m/s²

• 19.6 m/s²

How does the velocity of a ball change as it is thrown upwards?

• It fluctuates

• It remains constant

• It decreases

• It increases

At what point does a projectile reach its highest point?

• When it starts moving downwards

• When its velocity is zero

• When its velocity is maximum

• When its acceleration is zero

What happens to the velocity of a projectile after it reaches its highest point?

• It becomes zero

• It starts increasing in the opposite direction

• It remains constant

• It decreases further

How does gravity affect a projectile's motion on the Moon compared to Earth?

• It is weaker on the Moon

• It is stronger on the Moon

• It is the same on both

• It has no effect on the Moon

Can velocity and acceleration act in opposite directions?

• Only when an object is stationary

• No, they always act in the same direction

• Yes, for example, when a car slows down

• Only in space

What happens to a car's acceleration when it slows down at a red light?

• It accelerates forward

• It accelerates backward

• It decelerates

• It remains constant
