Hey Luna and Oliver, did you know that the gravitational pull between two objects is like a cosmic dance? It depends on the ____________________ of the objects and the ____________________ between them. Can you fill in the blanks?

Answer explanation

Gravitational pull depends on mass and the distance between the objects. The greater the mass, the stronger the gravitational pull, and the farther apart the objects are, the weaker the pull. Thus, the correct choice is mass/distance.

Imagine you're in a race with Anika and Elijah, and you want to speed up your go-kart. What should you increase to boost your acceleration and leave them in the dust?

Answer explanation

Acceleration of an object increases if the force increases, according to Newton's second law (F=ma). If mass increases while force remains constant, acceleration decreases.

Hey Charlotte and Michael, can you guess which type of wavelength packs more energy? Is it a ________________ wavelength?

Answer explanation

A short wavelength corresponds to higher energy due to the inverse relationship between wavelength and energy in the electromagnetic spectrum. Therefore, a short wavelength will have more energy.

Imagine Daniel and Scarlett are pushing a giant boulder from opposite sides with equal force. What will happen to the boulder?

Answer explanation

A balanced force results in no net force acting on an object, which means it will not cause movement. Therefore, the correct choice is 'no movement'.

Imagine Luna and Ethan are playing tug-of-war. An unbalanced force always causes ______________________ . What do you think happens?

Answer explanation

An unbalanced force always causes movement. This is because an unbalanced force results in a net force acting on an object, leading to a change in its state of motion.

Imagine you're a lazy cat named Maya, lounging on a sunny windowsill. What keeps you from moving unless absolutely necessary? Is it inertia or gravity?

Answer explanation

Inertia is the property of an object that resists changes in its state of motion. It can be thought of as the object's 'laziness' to change its motion, while gravity is a force that pulls objects toward each other.
