Physics Concepts

Airbag

• A device that inflates to cushion and protect passengers during a collision.

• A type of seatbelt that locks during sudden stops.

• A safety feature that deploys smoke to alert drivers of danger.

• A cushion that is used for comfort in car seats.

Speed

• How fast something is moving, without direction.

• The rate at which an object changes its position in a specific direction.

• The distance covered by an object in a given time period.

• The measure of how quickly an object can accelerate.

Newton’s First Law

• Things stay still or keep moving unless a force changes them.

• Objects in motion tend to stay in motion unless acted upon by an external force.

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

• Force equals mass times acceleration.

Velocity

• The speed of an object regardless of direction.

• How fast something is going and in what direction.

• The distance traveled by an object in a straight line.

• The rate of change of position of an object.

Mass

• The amount of energy in an object (measured in joules).

• How much matter is in something (measured in kilograms).

• The volume of an object (measured in liters).

• The weight of an object (measured in pounds).

Acceleration

• How quickly something speeds up or slows down.

• The rate at which an object moves in a straight line.

• The force applied to an object to change its direction.

• The distance covered by an object in a given time.

Seatbelt

• A safety strap in a car that keeps you from flying forward.

• A device that controls the speed of the car.

• A feature that enhances the car's audio system.

• A tool used for changing tires.

Motion

• Movement from one place to another.

• A state of rest or inactivity.

• The process of standing still.

• A change in temperature.

Outlier

• A point on the graph that does not fit the pattern.

• A point that is the average of a data set.

• A point that represents the median value.

• A point that is the most frequently occurring value.

Impact

• The force of one object hitting another.

• A type of energy transfer.

• The speed of an object in motion.

• The distance traveled by an object.
