Vocabulary
This is a push or a pull.
What is force?
This happens when A pulls with a 5 N force on one side of the car and B pulls with a 5 N force on the opposite side of a car.
What is nothing?
The standard unit for measuring force in the metric system.
What is a Newton (N)?
A force acting between surfaces in contact that resists motion.
What is friction?
An object that responds to magnetic force.
What is a magnet?
The sum of all the forces acting on a mass.
What is net force?
This happens when A pulls with a 3 N force on one side of the car and B pulls with a 5 N force on the opposite side of a car.
What is the car moves toward B?
An instrument used to measure force.
What is a spring scale?
A change to an object’s speed.
What is acceleration?
This is the invisible area of magnetic influence around a magnet.
What is a magnetic field?
This is the force that pulls all objects toward the center of the Earth.
What is gravity?
In class, students learned that a cart will move when a force of 50 N or greater is applied. This happened to the cart when a student pushed on the cart with a force of 10 N.
What is nothing?
The part of a motor that rotates when energy is transferred to it.
What is a shaft?
To squeeze or press.
What does it mean to compress?
The ends of a magnet where the magnetic force is strongest.
What are poles?
This is to act on and be acted upon by one or more objects
What is interaction?
Student A pushed on the cart with a force of 500 N. Student B pushed on the other side of the cart. The cart did not move. This is how much force student B applied.
What is 500 N?
Of two objects, Object A with 10 grams of mass and Object B with 50 grams of mass, the object that requires more force to move.
What is Object B?
A soccer ball is sitting on the ground. In addition to gravity, this is a force acting on the ball when it is sitting on the ground.
What is the force of the ground on the ball.
A piece of iron that only behaves like a magnet when under the influence of an external magnetic field.
What is a temporary magnet?
This is the force of gravity on a mass.
What is weight?
Student A pushed on the right side of the cart with a force of 400 N. Student B pushed on the left side of the cart. The cart rolled to the left. This student pushed with more force.
What is Student A?
Team A is pulling on a rope with a combined force of +400N. Team B is pulling in the opposite direction with a combined force of -550N. This is the net force on the rope.
What is -150N?
A dog sled was loaded with equipment, but on snow and ice, the dogs moved the heavy sled. Each dog pulled with a force of 600 N. During the race, the sled came to an area of grass and dirt instead of snow and slowed to a stop because of this.
What is friction?
The influence of a magnetic field on iron, which makes the iron act like a magnet.
What is induced magnetism?
