Air Resistance

A force caused by air, acting in the opposite direction of a moving object.

100

Pushing a car requires more force than pushing a shopping cart.

Is this an example of the 1st, 2nd or 3rd Law of Motion?

2nd Law of Motion

100

1st Law

An Object in Motion Stays in Motion

True or False: 

  • A heavier child on a swing needs more force to reach same height as a lighter child.

True

100

Force

A push or a pull that can cause the motion of an object to change. It has two important properties: strength and direction.

200

Acceleration

The speeding up of an object.

200

A still ball remains still until kicked.

Is this an example of the 1st, 2nd or 3rd Law of Motion?

1st Law of Motion

200
2nd Law

Heavier objects need a larger force to make them move.

200
  • A balloon moves in the opposite direction of air pushing out.

2nd Law

200

Balanced Force

When two equal forces act in opposite directions the result is that the forces are balanced and there is no motion.

300

Friction

A force resulting from two objects rubbing against each other. 

300

A ball bounces back with an equal force when thrown down.

Is this an example of the 1st, 2nd or 3rd Law of Motion?

3rd

300

3rd Law

For every action there is an equal and opposite reaction.

300

True or False: 

  • Newton's 1st law of motion is sometimes called the law of inertia.

True

300

Unbalanced Force

When one force is stronger than the other the result is motion.

400

Give me an example of when you would experience air resistance.

Answers will vary

Is this an example of the 1st, 2nd or 3rd Law of Motion?

1st Law of Motion

400
True or false: Friction is what keeps objects moving on forever

False

400

Motion

The process of moving or changing position.

500

Answers will vary.

500

A balloon moves in the opposite direction of air pushing out.

3rd Law

500

More friction means more heat! Give me an example of Friction

True: EXAMPLE PLEASE
