This law is often referred to as the Law of Inertia
What is Newton's 1st Law of Motion?
100
The definition of energy
What is the ability to do work?
100
Something that causes movement
What is a force?
100
Another name for a ramp (a slanting surface that connects a lower level to a higher levee) - the simplest of the simple machines.
What is an inclined plane?
100
The type of force used in a catapult.
What is a spring-like, elastic force? What is torsion?
200
The definition of inertia
What is the tendency of an object in motion to stay in motion and/or an object at rest to stay at rest?
200
Definition of Potential Energy
What is the stored energy a body has because of its position or arrangement?
200
The 2 types of forces used in the coin/index card experiment and the clothespin/index card/cup experiment.
What is a push and a pull?
200
A see-saw is this type of simple machine.
What is a lever?
200
The type of force used in a trebuchet.
What is gravity?
300
Newton's 2nd law describes how force, acceleration, and this are related. This is how much matter is in an object and is related to an object's weight.
What is mass?
300
Definition of Kinetic Energy
What is the energy that a moving body has because of its motion?
300
Gravity
What is the force that pulls things toward the Earth or any other object that has mass.
300
The point on which the lever moves or pivots.
What is the fulcrum?
300
According to Newton’s second law, if you have two objects with the same mass, the object that experiences a larger force will have a __________________ acceleration.
What is greater?
400
Newton's 3rd Law explained.
What is for every action there is an equal and opposite reaction?
400
A boulder at the edge of a high cliff has this type of energy.
What is potential energy?
400
The force that slows down objects that are rubbing against each other.
What is friction?
400
A wheel with this rod-like structure through its center lifts or moves loads.
What is an axle?
400
According to Newton's 2nd Law, if you have two objects with the different mass but same forces, the object with larger mass will experience a _________________ acceleration.
What is slower?
500
An experiment we conducted that shows Newton's 3rd Law in action.
What is the balloon on the straw and string? What is the canister experiment?
500
A car speeding down the road has this type of energy.
What is kinetic energy?
500
Two examples of forces frequently seen on the playground at recess.
What are (possible answers include:) pushing a swing, pushing and pulling on the comet; throwing the ball; pushing upward on the spider ropes (pulling up); running (pushing with muscles); balls falling down (gravity);
500
This simple machine uses grooved wheels and a rope to raise, lower or move a load.
What is a pulley?
500
The experiment that (tried) to demonstrate Newton's 2nd Law.
What is the balls of different sizes rolling down ramps to hit each other.
