• They never causes changes in motion

• They do not transfer energy to objects

• They can act on objects that are not touching

• They always cause objects to attract each other

• The greater the force applied, the slower the bicycle travels

• The greater the force applied, the greater the effect of friction on the bicycle's speed

• The greater the force applied, the greater the change in the bicycle's motion

• The greater the force applied, the less effect that mass has on the bicycle's motion
