Answer 49

Vertically downwards

Answer 50

Perpendicularly downwards to the object

Answer 51

Answer 52

Vertically upwards

Answer 53

Perpendicular to the surface producing it

Answer 54

Perpendicular to the object

Answer 55

Parallel to the object

Answer 56

There are no forces acting on a body

Answer 57

There is no resultant force

Answer 58

A body is completely still

Answer 59

A body is balanced

Answer 60

The turning effect of a single force

Answer 61

force x distance

Answer 62

force x perpendicular distance

Answer 63

weight x distance

Answer 64

force/distance

Answer 65

A pair of forces that are equal and opposite

Answer 66

The forces on an object

Answer 67

The sum of the clockwise moments of an object = the sum of the anticlockwise moments of an object

Answer 68

If an object is in equilibrium: the sum of clockwise moments = the sum of anticlockwise moments

Answer 69
