Term that
Force that attracts all objects?
An object with greater volume has greater gravity pull on it. Yes or No - Why?
No, mass is affected by gravity not volume.
If you have two objects one weighs 10kg and the other weighs 55 kgs. Which one requires more force to lift?
The 55 kg object
A force that acts on an object without physically touching it.
Non Contact Force i.e Gravity
Why do planets orbit the sun?
Gravitational pull.
The amount of matter in an object is called
MASS
Standard unit of measurement for weight
Newton (N)
What happens to an object at its farthest distance where gravity is weakest?
object slows down.
Can forces act on an object from multiple directions?
Bonus: Give an everyday example 100pts
Yes, friction acts to slow down a car or ball.
How are tidal waves affected on Earth?
Moons orbit and Gravitational pull
What is an Independent Variable (IV)?
A variable that is manipulated or changed within an experiment.
Acceleration is measured as _______.
Meters per second (m/s2)
If a crate weighs more on another planet than on earth. Why would this happen?
The planet has more mass and increased gravitational pull.
Why does the earth move in Orbit, but the Sun doesn't?
Sun has more Mass
a force that acts on an object after physical interaction.
contact force
While in orbit an object speeds up as what changes?
Distance
Gravitational force acting on an object results in an object's _______.
WEIGHT
Are volume and mass the same? why or why not
volume is how much space something takes and mass is how much stuff is in an object.
What makes a ball slow down and eventually stop?
Friction
How does decreasing distance between object affect their gravitational attraction?
It increases their gravitational attraction.
What reacts to changes of an independent variable?
dependent variable (dv)
Standard unit of measurement for MASS
Kilograms (kg)
On Earth, an astronaut with a mass of 100 kg has a weight of 735 N. On the Moon, the same astronaut has a mass of 100 kg and a weight of 123 N. Why?
Earth has greater mass and therefore, has a greater gravity.
Or
The moon as less mass and less gravity.
What type of force can repel objects?
magnetic force
The sum or difference of forces acting upon an object?
Net Force
