Sumo wrestler A applies a force of 70N to the right to sumo wrestler Z. Wrestler Z applies a force of 60 N back onto wrestler A. This is the resultant.
What is 10 N right?
100
An object in motion stays in motion with the same velocity, or an object at rest remains at rest, until acted upon by an unbalanced outside force.
What is Newton's 1st law (law of inertia)?
100
Varies with gravity; actually considered a force and should be measured in Newtons, but it is commonly measure with another unit.
What is weight?
200
I know a plane is moving faster than a car by using this.
What is frame of reference?
200
Increases with height or mass
What is gravitational potential energy?
200
Creates a change in the motion of an object.
What is an unbalanced force?
200
A basketball just before release has equal and opposite forces acting upon it.
What is Newton's 3rd law (law of action/reaction forces)?
200
Type of fluid friction that acts upon airplanes.
What is air resistance?
300
These can cause a change in velocity.
What is speed and/or direction?
300
Released when bonds between atoms are broken; food, batteries.
What is chemical potential energy?
300
Gravitational and magnetic force decrease when this increases.
What is distance?
300
At-a-distance, "unseen" force of attraction Newton discovered by applying his knowledge of his 1st law.
What is gravity?
300
Magnets have these characteristics and act differently when arranged when likes or opposites are combined.
What are (north & south) poles?
400
A downward-sloping line on a velocity-time graph.
What is negative acceleration or deceleration?
400
Energy can neither be created or destroyed; it can only be transformed.
What is the law of conservation of energy?
400
Gravity
Magnetism
What is are at-a-distance forces?
400
Another name for the law that states F=ma.
What is the law of acceleration?
400
Electricity pushes electrons through wires, creating a magnetic field around iron.
What is electromagnetism?
500
A horizontal line on a distance-time graph.
What is at rest or speed=0?
500
Increases with speed.
What is kinetic energy?
500
Visual representation of forces acting on an object; vectors show direction and magnitude of the forces and the resultant change in motion of the object.
What is a free-body diagram?
500
Example of Newton's 2nd law.
(answers vary - must explain how f=ma; more force-greater acceleration)
500
This is where moving magnets create an alternating current (AC) of electrons, producing electricity.
