What best defines potential energy?
Energy caused by motion
Energy an object stores because of its position or condition
Energy that cannot change into another form
Energy passed from one object to another through work
Between potential and kinetic energy, which is more useful for making objects move, and why?
Kinetic energy, since it involves movement
Neither contributes to the motion of objects
Both are equally important for motion
Potential energy, since it is stored for later use
A 5 kg rock is raised 2 meters and then dropped. What happens to its energy as it falls?
The rock’s kinetic energy changes into potential energy
Its potential energy turns into kinetic energy while falling
The rock loses all energy upon falling
All its potential energy disappears instantly
Look at the sorting activity in the diagram. Identify the error in energy classification.
Gasoline
Person using a hand-crank generator
Two skateboards:one moving and one at the ramp’s top
Fan spinning
Which describes kinetic energy correctly?
Energy moved from one object to another
Energy of an object because it is moving
Energy stored due to an object’s height
Energy resulting from sound waves
Which device changes kinetic energy into electrical energy?
Battery
Solar panel
Generator
Motor
What do we call a group of interacting components that function as one?
Apparatus
System
Instrument
Machine
What word describes the ability to cause motion?
Inertia
Energy
Momentum
Force
What term refers to energy moving from one object or system to another?
Conduction
Transfer
Conversion
Transformation
A wind turbine changes wind energy into electricity. Which process is this?
Energy storage
Energy conversion
Energy dissipation
Energy transfer
Choose which image does not demonstrate evidence of energy.
A flying soccer ball
A person turning a hand-crank generator
Light shining from a flashlight
A charged battery
What defines velocity accurately?
Distance per unit of time
Change in position of an object
Speed in a specific direction
Rate at which speed changes
In physics, what is meant by the term force?
The amount of matter in an object
The stored energy in an object
The rate at which motion changes
A push or pull that causes acceleration
When comparing two surfaces, what factor increases friction between them?
Smaller contact area
Smoother surface
Rougher surface
Lighter object
Which statement best explains how friction affects motion?
Friction helps objects move faster
Friction has no impact on motion
Friction increases the speed of moving objects
Friction resists motion between touching surfaces
Object A moves at a steady speed, and Object B speeds up in a straight line. Which one accelerates and why?
Neither, because both travel straight
Object A, because it moves constantly
Object B, because its speed is changing
Both objects, since they are moving
