Newton's INB Check for Understanding

A satellite orbiting the Earth

• Newton's 1st Law

• Newton's 2nd Law (Chat GPT says its not this one.)

• Newton's 3rd Law

Answer explanation

A satellite in orbit is a perfect example of Newton's 1st Law, which states that an object in motion stays in motion unless acted upon by an external force. The satellite continues its path due to inertia.

Earth orbiting the Sun

• Newton's 1st Law

• Newton's 2nd Law (Chat GPT says its not this one.)

• Newton's 3rd Law

Answer explanation

Newton's 1st Law states that an object in motion stays in motion unless acted upon by an external force. Earth orbits the Sun due to its inertia and the gravitational force from the Sun, illustrating this law.

A rocket blasting off into space

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Answer explanation

A rocket blasting off into space demonstrates Newton's 3rd Law, which states that for every action, there is an equal and opposite reaction. The rocket's engines push down on the ground, and in response, the rocket is propelled upward.

A speed skater that goes faster around the track as they push harder with their legs

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Answer explanation

Newton's 2nd Law states that acceleration is produced when a force acts on a mass. The skater accelerates faster by pushing harder, demonstrating the relationship between force, mass, and acceleration.

A picture hanging on the wall does not move

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Answer explanation

Newton's 1st Law states that an object at rest stays at rest unless acted upon by an external force. The picture on the wall remains stationary, illustrating this law as no force is causing it to move.

A magician pulls a tablecloth out from under dishes and the glasses

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Answer explanation

Newton's 1st Law states that an object at rest stays at rest unless acted upon by an external force. The magician quickly pulls the tablecloth, allowing the dishes to remain in place due to inertia.

A soccer ball accelerates faster than a bowling ball when the same amount of force is applied

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Answer explanation

According to Newton's 2nd Law, acceleration is directly proportional to force and inversely proportional to mass (F=ma). A soccer ball has less mass than a bowling ball, so it accelerates faster when the same force is applied.

F = M x A

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Answer explanation

The equation F = M x A represents Newton's 2nd Law of Motion, which states that the force acting on an object is equal to the mass of that object multiplied by its acceleration.

Your shoulder is pushed backward after shooting a shotgun

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Answer explanation

When you shoot a shotgun, the bullet moves forward, and according to Newton's 3rd Law, an equal and opposite reaction occurs, pushing your shoulder backward. This law explains the recoil experienced.

When you paddle a canoe, your oar goes backward, but you go forward

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Answer explanation

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. When you paddle backward with the oar, the canoe moves forward due to the force exerted on the water.
