● ‘Tensile force’ the force pulling things apart.5N
A force can manifest itself many different ways.
● ‘Cohesive adhesive force’ the force required hold things
together.

Definition
Force The presence force can only
be detected its effect body.
Example
A 50kg bag cement falls from forklift truck while being lifted storage shelf. Let consider few
examples:
● ‘Inertial force’ the force required get things moving, change
direction stop, like the motor car discussed above.
A force may cause stationary object move bring moving body to
rest.
A force may cause stationary object

force.
● ‘Compressive force’ the force pushing things together. For example, number people pushing broken-down motor
car exert force which propels forward, but applying the motor car
brakes applies force the brake drums which slows down stops

● ‘Friction force’ the force which resists prevents the movement
of two surfaces contact.
