A:

Q: In tearing a paper towel or plastic bag from roll ,why is sharp jerk more effective than a slow…

A: To understand this, you can use the concept of inertia and Newton’s second law of motion. Initially,…

Q: This is the friction that occurs between two objects that are not moving with respect to each other?

A:

A: A bungee jumper feels weightlessness when he jumps the platform. When the jumper is standing on the…

Q: is a push or a pull on an object. It can have different magnitudes and can be in different…

A: As per our guidelines we are supposed to answer only one question. Kindly re-post other questions as…

Q: If you push on a heavy box that is at rest, you must exert some force to start its motion. Once the…

A: From Newton’s first law of motion, it can be inferred that an object at rest or in motion remains at…

A: The situation is , a book at rest is pushed downwards.

Q: Why can you exert greater force on the pedals of a bicycle if you pull up on handlebars?

A: When we apply a pull force on the handlebars then it works as action force. And according to…

Q: How does the mass of an object affect its acceleration?

A:

Q: A 30 kg girl and a 40 kg boy stand on roller skates, face one another, and push off each other. If…

A: Newton's third law of motion state that, when two objects contact, they apply forces on each other…

Newton's First Law of Motion

If a very smooth ball is rolled down an inclined surface with zero friction, the ball will continue to roll indefinitely for an infinite time, in an attempt to reach to the same height on the opposite hill!
