Newton's Laws of Motion https://www.youtube.com/watch?v=kKKM8Y-u

Abigail and Emma are playing with a toy car. Sophia observes that the car continues to move even after Abigail and Emma stop pushing it. Which of Newton's laws of motion does this scenario illustrate?

• An object in motion will remain in motion, and an object at rest will remain at rest, unless acted upon by an unbalanced force.

• The net force is equal to the tension force minus the mass times small g.

• Force is equal to mass times acceleration.

• For every action, there is an equal but opposite reaction.

What is inertia?

• The force exerted by a surface to support the weight of an object resting on it.

• The force exerted on an object due to gravity.

• The force exerted by a rope or cable when it is pulled tight.

• The tendency of an object to keep doing what it's doing.

Hannah, Ava, and Emma are conducting a physics experiment. They are trying to calculate the net force acting on a car. Which equation should they use to find the net force?

• F(net) = tension force - mass x small g

• F(net) = m x acceleration

• F(net) = mg

• F(net) = ma

Abigail, Mia, and Zoe are playing a game of tug-of-war. When is the game in equilibrium?

• When the pulling force exerted by Abigail and Mia is equal to the pulling force exerted by Zoe, resulting in no change in the rope's position.

• The tendency of the rope to resist changes in its position.

• The force exerted by the ground to support the weight of the girls standing on it.

• The force exerted by the rope when it is pulled tight by the girls.

What is the normal force?

• The force exerted by a surface to support the weight of an object resting on it.

• The force exerted on an object due to gravity.

• The force exerted by a rope or cable when it is pulled tight.

• The force exerted by a moving fluid on an object moving through it.

What is the tension force?

• The force exerted by a surface to support the weight of an object resting on it.

• The force exerted by a moving fluid on an object moving through it.

• The force exerted on an object due to gravity.

• The force exerted by a rope or cable when it is pulled tight.

Lily is learning about physics and she came across a term that is also known as the force of gravity. Can you help Anika and Aiden tell her what it is?

• Acceleration

• Inertia

• Friction

• Weight

Ethan is studying physics and he comes across a problem where he needs to calculate the force of gravity acting on an object. He knows the formula but is confused about which one to use. Can you help Ethan identify the correct equation for the force of gravity?

• F(g) = tension force - mass x small g

• F(g) = ma

• F(g) = mg

• F(g) = net force - mass x acceleration

Jackson, Abigail, and Avery are studying physics together. They are discussing a book kept on the table. According to them, what is the net force on the book (an object in equilibrium)?

• The force exerted by the air in the room on the book.

• 0 N

• The force exerted by the table to support the weight of the book.

• The force exerted by the cover of the book when it is opened.

Maya and Emma are playing a game of catch. Ava observes that when Maya throws the ball, Emma catches it by applying an equal force in the opposite direction. Which of Newton's laws of motion does this scenario illustrate?

• The net force is equal to the tension force minus the mass times small g.

• An object in motion will remain in motion, and an object at rest will remain at rest, unless acted upon by a force.

• For every action, there is an equal but opposite reaction.

• Force is equal to mass times acceleration.
