Laws of Motion
This law of motion states that for every action, there is an equal and opposite reaction.
What is Newton's Third Law?
When the total net force acting on an object equals this specific number, the forces are considered balanced.
What is 0? (or zero Newtons)
Acceleration occurs whenever an object changes its speed or this other property of motion.
What is Direction?
The force needed to accelerate a 2 kg at 5m/s
What is 10 N
This law of motion states that for every action, there is an equal and opposite reaction.
What is Newton's Third Law?
Newton's First Law is often referred to by this six-letter word, defined as an object's tendency to resist changes in its state of motion.
What is Inertia?
Unlike balanced forces, unbalanced forces always cause an object to change its motion by doing this
What is Accelerate? (Acceptable: speed up, slow down, or change direction)
When a car comes to a red light and slows down, it is experiencing this type of acceleration, often referred to as deceleration.
What is Negative Acceleration?
A 10kg}bowling ball pushed with a net force of 50N will accelerate at this rate.
What is 5m/s
Unlike balanced forces, unbalanced forces always cause an object to change its motion by doing this.
What is Accelerate? (Acceptable: speed up, slow down, or change direction)
Newton’s Second Law is most famous for this concise, 3-letter mathematical formula relating net force, mass, and acceleration
What is {F = ma}
In a game of tug-of-war, Team A pulls to the left with 200 Newtons of force while Team B pulls to the right with 150 Newtons. The overall net force and direction acting on the rope is this.
What is 50 Newtons to the left?
A roller coaster cruising along a completely straight track at a constant speed of 45 mph has an acceleration value equal to this number.
What is Zero?
If a force of 100N at 4m/s the object's mass must be this many kilograms.
What is 25 kg
A 10kgbowling ball pushed with a net force of 50N will accelerate at this rate.
What is 5m/s
If a 1,200 kg car accelerates at 3 m/s the net force acting on the vehicle is this many Newtons.
What is 3,600?
A book sitting perfectly still on a desk experiences balanced forces because the upward normal force from the desk balances out this downward force.
What is Gravity? (or weight)
On a speed-vs-time graph, a straight horizontal line indicates zero acceleration, while a line sloped upward represents this.
What is Constant (or Positive) Acceleration?
If you double the force applied to an object while keeping its mass the same, the acceleration will change by doing this.
What is Doubling?
On a speed-vs-time graph, a straight horizontal line indicates zero acceleration, while a line sloped upward represents this.
What is Constant (or Positive) Acceleration?
When a tablecloth is quickly pulled out from under a set of dishes without knocking them over, this specific property of matter—and Newton’s First Law—is on full display.
What is Inertia? (Acceptable: Newton's First Law)
Even though a race car traveling in a circle at a constant speed of 100 mph has a steady speed, the forces acting on it are unbalanced because it is constantly changing this.
What is Direction? (Acceptable: Velocity)
A runner maintaining a steady speed of 6 mph while rounding a sharp curve on a track is still accelerating because of this change.
What is Changing Direction (or changing velocity)?
Two students push a 50kg box in the same direction—one pushes with 30N and the other with 20 N. The resulting acceleration of the box is this value.
What is 1 m/s
Even though a race car traveling in a circle at a constant speed of 100 mph has a steady speed, the forces acting on it are unbalanced because it is constantly changing this.
What is Direction? (Acceptable: Velocity)
