Imagine you are playing on a playground with a friend. Your friend is sitting on a swing, and you want to give them a push. You push your friend with a lot of force, and they start swinging back and forth. Why does your friend swing forward when you push them? Select the appropriate Newton’s Law to reflect the activity.

• According to Newton's first law of motion, an object at rest will stay at rest unless acted upon by an external force.

• According to Newton's second law of motion, the force you applied to your friend's swing caused their acceleration in the forward direction.

• According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Your push on your friend's swing resulted in an equal and opposite force that propelled them forward.

You and your friends are building toy cars to race down a ramp. You notice that some cars go faster than others. What could you do to make a toy car accelerate more quickly down the ramp? Select the appropriate Newton’s Law to reflect the activity.

• According to Newton's first law of motion, you could make the car heavier to increase the force of gravity acting on it, causing it to accelerate faster.

• According to Newton's second law of motion, you could increase the force applied to the car by giving it a more powerful push, causing it to accelerate faster.

• According to Newton's third law of motion, you could decrease the friction between the car and the ramp, reducing the opposing force and allowing the car to accelerate more quickly.

You and your classmates are conducting an experiment with balloon rockets. You blow up a balloon and attach it to a straw with a string. When you let go of the balloon, it zooms across the string. Why does the balloon rocket move?

• According to Newton's first law of motion, the balloon rocket moves because of the force applied to the air inside the balloon, causing it to be expelled and propelling the rocket forward.

• According to Newton's second law of motion, the force applied to the air inside the balloon creates an acceleration that propels the rocket forward.

• According to Newton's third law of motion, the force of the air being expelled from the balloon creates an equal and opposite force that propels the rocket forward.

Sarah has a heavy box that she wants to lift onto a shelf. She knows that she cannot lift it directly, so she finds a long plank and places it underneath the box. By pushing down on one end of the plank, Sarah slowly lifts the box onto the shelf. What simple machine is Sarah using to lift the heavy box?

• Plank

• Wedge

• Ramp

• Wheel and Axle

Sarah has a heavy box that she wants to lift onto a shelf. She knows that she cannot lift it directly, so she finds a long plank and places it underneath the box. By pushing down on one end of the plank, Sarah slowly lifts the box onto the shelf. Why is using the plank helpful in lifting the box?

• The wheel allows easy travel

• Plank is a lever to lift up

• Wedge is used to change levels

• Sarah just gives up and asks a friend
