Force
This is defined as a push or a pull acting on an object.
force
If you know a cross-country runner ran 4 km in 15 minutes, this is the specific physical quantity you can calculate.
Speed
This law states that an object at rest stays at rest unless acted upon by an unbalanced force.
Newton’s 1st Law.
This type of friction exists between a desk chair and the floor when the chair is not moving.
static friction
The Speeding Snail If a super-powered garden snail travels at a speed of 67 centimeters per hour for exactly one hour, this is the total distance the snail has covered.
67 centimeters
If one dog pulls a rope 5N to the left and another pulls 3N to the right, this is the direction the rope will move
To the left (5N Left vs. 3N Right = 2N Net Force Left)
A bus drives 110 km in 2 hours, 65 km in 1 hour, and 70 km in 2 hours. This is the bus's average speed for the whole trip.
49 km/h.
Work: Total distance is 110+65+70=245 km. Total time is 2+1+2=5 hours. 245÷5=49
"For every action, there is an equal and opposite reaction" describes this specific law.
Newton’s 3rd Law.
A skydiver falling through the air is an example of this type of friction.
fluid fricition
Newton’s Lazy Cat According to Newton’s 1st Law, if a fat cat named "Sir Purrs-a-Lot" is napping on a sofa with 67Newtons of force, he will stay there forever unless he is acted upon by this type of force (like the sound of a tuna can opening).
an unbalanced force
When the forces on an object are equal in size and opposite in direction, they are called this.
balanced forces
To find average speed, you must divide this by the total elapsed time.
Total distance
Newton’s 2nd Law states that Force is equal to these two variables multiplied together.
Mass and acceleration
If Team A pulls with 50N to the left and Team B pulls with 40N to the right, this is the net force.
10N to the left
The Banana Peel Slip In a cartoon, a character slides across the floor after stepping on a banana peel. If there are 67banana peels on the floor, the character is failing to create enough of this specific type of friction to stay upright.
sliding friction
If a box has 7N of force to the right and 21N of force to the left, this is the resulting net force and direction.
14N to the left (21N - 7N = 14N).
According to the formulas provided, total distance divided by speed equals this.
Time (T)
When a soccer player kicks a ball, the reaction force is the force applied to this by the ball.
The foot (Force applied to the foot by the ball).
This is the net force on a football thrown with 20N of force to the right against 5N of wind resistance.
15N to the right (20N−5N=15N)
The Great Tug-O-War In a weird Tug-O-War match, 100 puppies pull to the left with 67 Newtons of force, while a single giant hamster pulls to the right with 67 Newtons of force. This is the net force of the match.
