Force
A push or pull exerted on an object is called what?
Force
This is the rate at which an object moves over time.
Speed
This force resists movement between two surfaces in contact.
Friction
Along with the Law of Universal Gravitation, who created the three Laws of Motion in the late 1600s?
Isaac Newton
We worked against this force in the egg drop activity.
Gravity
The speed and direction of an object is called what?
Velocity
Can an object accelerate beyond light speed?
No
Objects remain at rest or in motion, unless what?
Acted upon by a force.
This describes the amount of matter in an object.
Mass
The rate at which an object's velocity changes over time is called what?
Acceleration
The tendency of objects to resist changes in motion is called what?
Inertia
Can an object's speed and direction change without a force acting on it?
No
Under the force of gravity, objects with mass have what? (It was important to keep this low during the egg drop.)
Weight
Objects in motion have this: a measure of mass and velocity.
Momentum
We used this force to slow the acceleration of our falling eggs.
Air resistance
Force equals mass times what?
Acceleration
This force causes objects to rotate.
Torque
Sometimes, forces act over time. The resulting change in momentum is called what?
Impulse
This device can detect or resist changes in orientation with its angular momentum. It has many uses, including as a toy, in aircraft, and in mobile phones.
Gyroscope
For every action, there is what?
An equal and opposite reaction
