What Is Gravity?
This is the force of attraction between any two objects that have mass.
What is Gravity?
This is the amount of matter (stuff) in an object, measured in grams or kilograms.
What is mass?
This is what happens to gravitational pull as two objects get farther apart.
What is it gets weaker?
This is the force that pushes against a falling object, caused by air.
What is air resistance?
This is roughly the gravity multiplier for the Moon compared to Earth.
What is 1.6N/kg (1/6)
According to legend, this scientist supposedly got the idea for gravity after an apple fell on his head.
Who is Isaac Newton?
This is the force of gravity acting on an object's mass, measured in Newtons.
What is weight?
This is what happens to gravitational pull as an object's mass increases.
What is it gets stronger?
A flat sheet of paper falls slower than the same paper crumpled into a ball because of this.
What is more air resistance (more surface area)?
This planet's gravity is about 38% of Earth's gravity
What is Mars? (3.72 m/s²)
This is the general term for any push or pull on an object.
What is a force?
This property of an object stays exactly the same on Earth, the Moon, or Mars.
What is Mass?
This is why astronauts on the International Space Station appear to float, even though gravity still acts on them.
What is they are continuously falling around (orbiting) Earth?
This term describes the point where air resistance balances gravity, so falling speed becomes constant.
What is terminal velocity?
This parachute design feature increases air resistance the most.
What is surface area?
This is how strongly Earth’s gravity pulls on objects near its surface.
what is 9.8m/s^2?
If your mass on Earth is 50 kg, this is your mass on the Moon.
What is 50 kg?
Between the Moon and Jupiter, this one has the stronger gravitational pull.
What is Jupiter?
This force increases sharply when a skydiver opens their parachute, slowing them down.
What is air resistance?
Standing on this planet would make you feel heavier than you do on Earth.
What is Jupiter?
This is how strongly the Moon’s gravity pulls on objects near its surface.
What is 1.6m/s^2?
This is the unit used to measure weight.
What is the Newton (N)?
This is the term for the curved path an object takes around another object (like the earth and moon), caused by a balance of forward motion and gravity.
What is an orbit?
This property stays exactly the same for the flat paper and the crumpled paper, even though they fall at different speeds.
What is their mass?
This is a reason a parachute's actual descent time might not match its predicted time, even with a good design.
What is: air leaks, an imperfect build, wind, or timing error?
