I pull things down but you don’t see me. What am I?
Gravity
I change speed or direction when a force acts on me. What law explains me?
Newton’s First Law of Motion
I am the resistance that slows down motion between surfaces. What am I?
Friction
I am the point where all forces balance and an object does not rotate. What am I?
Center of mass
I am what you measure with a thermometer. What am I?
Temperature
I am formed when liquid turns into gas. What process am I?
Evaporation
I am the process where light bends when it passes through different media. What am I?
Refraction
I am a wave that needs no medium and can travel through space. What am I?
Electromagnetic wave
I am the state of matter that flows and takes the shape of my container. What am I?
Liquid
I am the unit used to measure force. What am I?
Newton
I describe how much matter is packed into a space. What am I?
Density
I am the quantity that describes force over time change. What am I?
Impulse
I am energy from the sun that helps plants grow. What am I?
Light energy
I store energy when stretched or compressed. What am I?
Elastic potential energy
I am the energy stored in motion. What am I?
Kinetic energy
I am the law that explains why energy cannot be created or destroyed. What am I?
Law of Conservation of Energy
I have no shape of my own, but I can fill a balloon and help you breathe. What am I?
Gas
I am the measure of how fast an object changes position over time. What am I?
Speed
I am the law that says every action has an equal and opposite reaction. What am I?
