Newton's Laws

Front

A squid moves through the water by ejecting water out of its body into the surrounding water. When the water is pushed out, the ejected water pushes back and thrusts the squid forward.

Back

Third Law of Motion (law of motion and reaction)

Front

Which example best demonstrates an application of Newton's first law of motion?

Back

A child tries to push sofa across the floor, but it will not move. His sister comes to help him. Pushing together, the children are able to move the sofa.

Front

What effect does the carpet's frictional forces have on the motion of the box when a force of 5 Newtons is applied and an opposing force of 2 Newtons is present?

Back

The box moves to the left at a slower speed because of a lesser net force of 3 Newtons.

Front

Which object's motion exemplifies Newton's third law of motion?

Back

A rocket forces gas in a downward direction to launch itself into the air.

Front

Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction. Which Newton's Law is being used in this example?

Back

Newton's 3rd Law (Law of Action-Reaction)

Front

Why is pushing a child on a swing easier than pushing an adult on the same swing?

Back

Newton's 2nd Law (Law of Acceleration)

Front

Why does a soccer ball accelerate more than a bowling ball when thrown with the same force of 20 Newtons? Which of Newton's Laws of Motion explains this?

Back

Newton's 2nd Law (Law of Acceleration)

Front

What law explains why Damian's coffee spilled when he stopped suddenly?

Back

Newton's 1st Law (Law of Inertia)

Front

A crash test dummy is used to test the durability of a new car seatbelt technology developed by Besla electronics. During the first test, the seat belt failed and resulted in the dummy being ejected as seen in the pictures. Which law of motion explains why the dummy ejected in that fashion?

Back

Newton's 1st Law (Law of Inertia)

Front

An action-reaction pair forces exists between which? (Options: The aerialist's feet and the rope, The rope and the balancing bar, The two ends of the rope, The aerialist's arms and legs)

Back

The aerialist's feet and the rope
