Noon time in summer solstice.
Lunar eclipses can occur only during a ____.

Astronomy
Johannes Kepler’s Laws of Planetary Motion describe the planets’ movement as:
Elliptical paths around the Sun.
Brahe’s observations disproved the prevailing view of the solar system because they showed:
The stars are fixed in their positions.
Which of the following statements accurately describes the shape of planetary orbits according to Kepler’s first law?
Planets move in elliptical paths with the Sun at one focus.
Tycho Brahe’s extensive data on planetary positions was crucial for:
Kepler to formulate his laws of Planetary Motion.
One of Kepler’s Laws states that a planet’s speed varies depending on its:
Distance from the Sun.
Physics
Which of the following elements, according to Aristotle, would a rock return to if thrown upward?
Earth.
Which of the following is Galileo’s assertion on horizontal motion?
When an object is left alone, it will continue to move with constant velocity.
A boy was pushed from a height of a water slide. According to Aristotle, which of the following is true about this scenario?
The boy experienced a violent motion due to an external force.
A ball is rolling to the right on a friction-free surface. If the ball is pushed to the right, what will happen to its motion?
The ball will increase its speed.
Based on Galileo’s experiments, when do you say that motion is uniformly accelerated?
When speed is proportional to time of travel.
A feather and an iron bar are released from the same height in a room without any air resistance. If you are an Aristotle follower, which will fall first?
Both at the same time.
According to Aristotle, which falls faster, heavier or lighter object?
Heavier object.
A rolling ball was found to pick up a speed of 2m/s every second. What will be its speed after 5 seconds if it started with 0m/s at 0s?
10m/s.
Three objects X, Y, and Z, with masses of 6 kg, 8 kg, and 16 kg, respectively, were dropped simultaneously. Provided that there is no air resistance, which object will first reach the ground?
Objects X, Y, and Z will fall at the same time.
If two objects with different masses are dropped simultaneously from the same height in a vacuum, they will:
Reach the ground at the same time.
A piece of paper is at rest on your desk. Which of the following statements best describes this situation?
The forces acting on the paper are balanced.
All statements below have similarities to Galileo’s assertion on horizontal motion and Newton’s 1st law of motion, except ____.
All objects have inertia that tends to increase or decrease its speed.
A change to an object's motion is caused by ____.
Unbalanced forces.
When a balloon held between the hands is pressed, its shape changes. This happens because:
Balanced forces act on the balloon.
Which of the following balls has the greatest inertia?
A bowling ball.
