200
If an equal force acts on a pencil and a text books, which one will have GREATER acceleration?
Pencil
200
If I traveled 100 miles in 2 hours, what was my speed?
50 mi/hour
200

This quantity, measured in kg·m/s, is calculated as mass times velocity.

What is momentum?

300
Every action has an equal and opposite reaction.
Newton's Third Law
300

The leader of an organization, group, or company

CEO - "Chief Executive Officer"

300
Gravity is NOT force. True or False?
False - gravity IS a force.
300
If I am slowing down in the car, is that acceleration?
YES
300

This is the term for the overall force when multiple forces combine to zero, resulting in no acceleration.

What is balanced force (or net force of zero)?

400
Wearing seat belts to protect passengers when a car stops quickly is an example of which law?
Newton's First Law
400

The push exerted on one object when it has a collision with another object; just one of the pair of equal-sized forces in a collision

Impact Force

400

Inertia is a force. True or False.

No, inertia is not a force—it’s this property of matter that makes objects resist changes to their motion, as explained by Newton’s first law.

400
Turning a corner is an example of acceleration. True or False
True
400

The standard unit of force in the metric system, equal to the force needed to accelerate 1 kg at 1 m/s².

Newton

500
If I am sitting in my chair, gravity pushes down on me. What is the opposite and equal force in this scenario?
The chair pushing UP on me.
500

Most successful, considering the situation

Optimal

500
What type of force slows down a skateboarder when he puts his foot down to brake?
Friction
500
Acceleration is the rate at which inertia changes over time. True or False?
FALSE - Acceleration is the rate at which VELOCITY changes over time.
500
Everything in the universe is in _____________.
Motion
600

When you push on a wall, the wall pushes back just as hard—Newton’s 3rd law in its simplest form: forces always come in these equal-but-opposite twins.

What are action-reaction pairs?

600

Repeating a process in a way that considers the results of a previous design

Iterative Testing

600

Two forces are this type when they are equal in size, opposite in direction, and cause no change in motion.

What are balanced forces?

600

A flat line on a speed-time graph means this value for acceleration.

What is zero (or constant speed)?

600

The creator of Newton’s Laws was born on Christmas Day 1642 in a tiny farmhouse near Grantham; today you can visit his apple tree in this European country where tea, crumpets, and gravity all fall down.

What is England? (or the United Kingdom)
