OFTF- What is the first stage of an object falling through fluids. What is the air resistance, resultant force and acceleration like?
Object starts to fall slowly. Air resistance small compared to weight of object. Large resultant force and object accelerates quickly
1 of 8
OFTF- What is the second stage of an object falling through fluids. What is the air resistance, resultant force and acceleration like?
Object accelerates, air resistance still increasing. Wight stays same. Resultant force decreasing.
2 of 8
OFTF- What is the third stage of an object falling through fluids. What is the air resistance, resultant force and acceleration like?
Air resistance and weight of object equal. Resultant force= Zero. Object falls at steady speed. Called TERMINAL VELOCITY.
3 of 8
What is the mass of asn object and what is it measured in?
The amount of matter an object is made from and is measured in kilograms (kg)
4 of 8
Is the mass of an object the same on all planets?
Yes
5 of 8
What is weight and what is it measured in?
It's a force and measured in newtond (N)
6 of 8
What 2 components does weight depend on?
Mass and gravitational field strength
7 of 8
Why is weight different on different planets? What is the formula to find weight?
Because of the gravitational feild strength of the planet/ Weight= Mass x Gravitational field strength
