Turning Effect

Question 1

Calculate moment using the product force and perpendicular distance from a pivot

Answer 1

moment=product force x perpendicular distance

Question 2

What is the principle of moments

Answer 2

When a body is balanced, the total clockwise moment about a point is equal to the total anticlockwise moment

Question 3

Conditions for equilibrium

Answer 3

1. Net force of the object is zero

2. Experiencing no acceleration

Question 4

Difference between scales and vectors

Answer 4

Vectors have direction and magnitude, scale only has magnitude

Question 5

Example of Scalars

Answer 5

Speed, energy, mass and time

Question 6

Exaple of vectors

Answer 6

Velocity, displacement, momentum

Question 7

Describe the effect of the position of center of mass on the stability of simple objects

Answer 7

The lower the center of mass, the more stable the object. If the center of mass is higher, the more likely the object to tilt if it is pushed over
