You probably have heard of ‘antibiotic resistance’ before, but most people don’t realise that it’s actually the bacteria that become resistant to the antibiotics, not humans or animals. Antibiotics are a type of medicine that are used to...

Inertia is the resistance to a change in motion. So an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by an unbalanced force.
