Fill in the blanks:

A force can be drawn using force

Forces always come in pairs. The pairs are called...

• attractive pairs

• interaction pairs

• connecting pairs

• close pairs

How do you measure forces?

• with a newtonmeter

• with a ruler

• with a stopwatch

• with a ruler and stopwatch

What does Hooke's Law state

• When the extension doubles when you double the force

• When the distance doubles when you double the force

• When the length of a string doubles

Define the term "equilibrium"

• when an object moves rapidly

• when an object doesn't move because the forces cancel out

• when an object slows down

Forces are measured in the unit...

Contact forces occur when objects are touching, examples of these include:

• friction, gravity, pull

• push, pull, friction

• friction, air resistance and water resistance

• friction, gravity, push
