Forces and Motion
This law explains the relationship between force, mass, and acceleration.
What is Newton's Second Law?
This quantity equals mass times velocity.
What is momentum?
This force pulls objects towards Earth.
What is gravity?
Energy associated with motion is called this.
What is kinetic energy?
This force keeps planets orbiting the Sun.
What is gravity?
A 4 kg object experiences a net force of 20 N. This is its acceleration.
What is 5 m/s2.
When two objects stick together after a collision, the collision is called this.
What is an inelastic collision?
If distance between two masses increases, gravitational force does this.
What is decrease?
Energy stored due to height above the ground is called this.
What is gravitational potential energy?
This happens to your body in a car when the driver suddenly slams on the brakes.
What is inertia (or continuing to move forward)?
This quantity has both magnitude and direction.
What is a vector?
A 2 kg cart moving at 6 m/s has this momentum.
What is 12 kg·m/s?
In a series circuit, this quantity remains constant.
What is current?
A 2 kg object moving at 5 m/s has this kinetic energy.
What is 25 J?
A skateboarder at the top of a ramp has the greatest amount of this type of energy.
What is gravitational potential energy?
If the same force acts on a larger mass, this happens to its acceleration.
What is acceleration decreases.
This quantity is conserved in all collisions within a closed system.
What is momentum?
A 9 V battery connected to a 3 Ω resistor produces this current.
What is 3 A?
According to this law, energy cannot be created or destroyed.
What is the Law of Conservation of Energy?
This electrical device converts electrical energy into light energy.
What is a light bulb?
A rocket pushing exhaust gases downward demonstrates this Newton's Law.
What is Newton's Third Law?
Seat belts and airbags reduce injuries by increasing this during a collision
What is stopping time?
The slope of a voltage-current graph represents this electrical quantity.
What is resistance?
At the lowest point of a roller coaster, this form of energy is greatest.
What is kinetic energy?
A roller coaster slows down over time because of this force acting between surfaces.
What is friction?
