Weight and Terminal Velocity

Question 1

What is Terminal Velocity?

Answer 1

The maximum velocity that an object can travel in a fluid

Question 2

What is a Balanced Force?

Answer 2

Balance forces are two forces acting in opposite directions on an object, and equal in size

Question 3

What is a Unbalanced Force?

Answer 3

Forces that cause a change in motion of objects are called unbalanced forces

Question 4

What is the Formula for Force?

Answer 4

Force = Mass x Acceleration

Question 5

What is weight?

Answer 5

The weight of an object is the force acting on it due to gravity

Question 6

What is Mass?

Answer 6

The Mass of an object depends on the quantity of matter in it.

Question 7

What is the Equation for weight?

Answer 7

Weight = Mass x Acceleration due to Gravity

Question 8

What is the Equation for Acceleration due to gravity?

Answer 8

Weight/mass

Question 9

What is the Equation for Total Stopping Distance?

Answer 9

Total stopping distance = Thinking Distance + Braking Distance

Question 10

How do you calculate Braking Force?

Answer 10

a = v^2 – u^2 / 2xS

Question 11

What does A stand for in the Equation for Braking Force?

Answer 11

A = Acceleration

Question 12

What does V stand for in the Equation for Braking Force?

Answer 12

V= final velocity

Question 13

What does S stand for in the Equation for Braking Force?

Answer 13

S = Displacement

Question 14

What does U stand for in the Equation for Braking Force?

Answer 14

u = Final Velocity

Question 15

How do yo you find Final Velocity (U) using the Brake force formula?

Answer 15

U = Square root(-(2as-V^2))
