Dynamics

Imagine you're on a merry-go-round, spinning in a perfect circle. Which way do you think the invisible force is pulling you to keep you moving in that circle?

• Away from the center of the merry-go-round

• Along the edge, like you're trying to fly off

• Towards the center, like a string pulling you in

• Opposite to your merry-go-round horse's direction

Imagine you're a superhero, and you've just discovered you have the power of super strength! Now, when you push objects, they zoom away. According to Newton's second law of motion, the speed at which they zoom is directly proportional to the force of your push and inversely proportional to its:

• speed

• mass

• volume

• density

Imagine you're in a spaceship floating in the vastness of space, and all of a sudden, all engines turn off, making the net force acting on the spaceship zero. According to Newton's first law of motion, what will happen to your spaceship?

• accelerate indefinitely

• stop abruptly

• move in a circular path

• remain at rest or continue moving at a constant velocity in a straight line

Imagine you're a wizard standing atop a towering castle. You have two enchanted stones of different masses. With a flick of your wand, you release them from the same magical height. Ignoring the whispers of the wind (air resistance), which stone reaches the kingdom's ground first?

• The feather-light stone zooms down first.

• Both stones land with a thud at the same moment.

• The stone with the broadest enchantment (surface area) takes the lead.

• The stone heavy with ancient magic falls faster.

Imagine you're a superhero, and you've just applied a force of 20 N to a villain's getaway car of mass 5 kg. What's the acceleration of the car as it zooms away?

• 2 m/s^2

• 4 m/s^2

• 6 m/s^2

• 8 m/s^2

Imagine you're on a magic carpet, gliding smoothly through the sky at a steady pace. What does this tell us about the invisible forces at play?

• The invisible forces are having a party and increasing their strength

• The invisible forces are perfectly balanced, as all things should be.

• The invisible forces are dancing around, changing their direction

• The invisible forces are getting tired and decreasing their strength

Imagine you're in a car zooming down a straight road at a steady pace. Which of these statements do you think is spot-on?

• The car is picking up speed

• The car isn't speeding up or slowing down

• The car is taking a sharp turn

• The car is hitting the brakes

Ready to test your physics prowess? Let's dive into the world of forces! What is the unit of force in the International System of Units (SI)?

• Newton

• Joule

• Pascal

• Watt

Imagine you're in space and you decide to move twice as far away from your astronaut friend. What magical transformation happens to the gravitational pull between you two?

• It stays put, no change at all

• It doubles - more space, more force!

• It decides to take a break and halves

• It becomes shy and reduces to a quarter of its original self

🌟 Pop Quiz Time! 🌟 Can you identify which of these is a scalar quantity? Hint: It's not about direction, but magnitude!

• Velocity - The speedy roadrunner!

• Acceleration - Faster, faster!

• Force - May the force be with you!

• Mass - How heavy are you?
