Question | Answer |
---|---|
Forces include... | magnetism, friction and gravity |
Forces are... | pushes and pulls |
The force of gravity will always... | pull towards the center of Earth |
Increasing friction will... | slow an object down. |
Decreasing friction will... | cause an object to move more freely. |
Objects such as iron and steel are... | attracted to magnets. |
Opposite poles of magnets... | attract. |
Like poles (same poles) of magnets... | repel. |
Force is measured in... | newtons (N). |
A spring scale is... | a tool used to measure force. |
force | a push or pull that acts on an object. |
gravity | the force of attraction between any two objects |
motion | the act of moving from one place to another |
friction | the force that results when 2 materials rub against each other or then their contact prevents sliding |
shape | the form or outline of an object |
inertia | the tendency of an object to resist any change in motion |
kinetic energy | energy due to motion |
potential energy | energy that is not causing any changes now but could cause changes in the future; stored energy |
