Forces and Motion
What force pulls objects towards the Earth
What is Gravity!
What form of energy does a moving object have?
What force pushes objects upward in water?
What is buoyancy?
What causes an object to move or stop?
What is a force?
What are the three states of matter?
What is used to measure how fast something is moving?
What is Speed?
What kind of energy is stored in a stretched band?
Why do some objects float in water while others sink?
What is because of differences in density?
What is Friction?
What is a force that resists motion between two surfaces?
What units are used to measure force?
What are Newtons (N)?
What happens to an object's motion if it is acted upon by an object with equal force?
What is it comes to a stop?
Name two forms of energy when you push an object?
What is mechanical energy/Kinetic energy/etc.
What happens to the buoyant force if you submerge more of an object (does it increase/stay the same/decrease)?
What is Inertia?
What is the tendency of an object to resist changes in motion?
What is mass a measure of?
What is Friction?
Why does a ball rolling on the ground eventually stops, even if no one touches it?
What is because of Friction?
Why does a steel ship float while a small steel ball sinks?
What is the formula for force according to Newton's 2nd Law?
What is Force = Mass x Acceleration (F = ma)?
How is mass different from weight?
What is mass is the same everywhere, and weight depends on gravity?
If two objects with different masses are pushed with the same force, which one accelerates more and why?
How does the Law of Conservation of Energy apply to a pendulum swinging back and forth?
A block of wood floats with 1/4 of it above water. What does this say about its density compared to water.
What is its density is 75% that of water (because 3/4 of it is submerged)?
What is because it has more mass, therefore requiring a greater force?
What is it would be less because the Moon has less gravity to push you down?
