With the help of an experiment or an activity, show and verify the following:
- If two forces are in the same direction and they act on an object. So, the net force on the object is sum of the two forces and the direction of this net force is along the direction of the force greater in magnitude.
-If the forces are equal then the net force is 0.If one force is greater than the other than whatever is having the two forces exerted on it will move in the direction of the greater force's direction. The total force will equal the greater force - lesser force.
Perform an activity or an experiment to show that "Force = mass x Acceleration due to gravity".

As you know, pressure is the force per unit area. Liquid pressure at a depth is the weight of the liquid above that point. Then prove and show , with the help of an experiment that : "This weight will be equal all over the same depth regions. "
With the help of an experiment or an activity, show and verify the following:
- When two unequal forces act on a body in opposite direction, then the effective force is equal in magnitude to "the difference of the two forces" and acts in the greater force direction.
{Please don't provide any web link or certified answer .. I want only experts answer ... If possible, then experts please provide a picture for the demonstration for a better understanding} - If two forces are in the same direction and they act on an object. So, the net force on the object is sum of the two forces and the direction of this net force is along the direction of the force greater in magnitude.
-If the forces are equal then the net force is 0.If one force is greater than the other than whatever is having the two forces exerted on it will move in the direction of the greater force's direction. The total force will equal the greater force - lesser force.
