Two types of objects that are often hard to tell apart are identical twins and look-alike objects. Identical twins share the same genetic makeup, making it challenging to differentiate them based on physical appearance. Look-alike objects, such as counterfeit products, mimic the appearance of genuine items, making it difficult to distinguish between them without closer inspection.
You can tell when an object has been statically charged if it attracts or repels other objects, causes a spark when touched, or gives you a mild shock when you touch it. Objects can become statically charged through friction or contact with other charged objects.
You can tell that an electroscope is charged by observing the divergence of the leaves. If the leaves spread apart after bringing a charged object close to the electroscope, it indicates that the electroscope has acquired a charge.
You can tell if one object has more mass than another by comparing their weights. The object with a greater weight typically has more mass. You can also compare the density of the objects - denser objects usually have more mass.
Velocity tells us the speed at which an object is moving and the direction in which it is moving.
An object has buoyancy if it can float in a fluid, such as water. This is because buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. Objects that are less dense than the fluid they are in will float, while objects that are more dense will sink.
