Force (f) that is acting on an object is equal to the mass (m) of an object times its acceleration (a). If objects collide, the total momentum before the collision is the same as the total momentum after the collision. Force or pressure that attempts to flatten or squeeze a material. The pulling force exerted by a string, cable, chain, or ...

There are three types of intermolecular forces: Induced dipole – dipole forces also called van der Waals or London dispersion forces. Permanent dipole – dipole forces are the attractive forces between two neighbouring molecules with a permanent dipole. Hydrogen Bonding are a special type of permanent dipole - permanent dipole forces.
change speed. change direction. change shape. The effects of forces on an object often depend on the type of force acting. The push force (thrust) of an engine can cause a car to speed up, whilst the force exerted by the brakes (friction) can cause it to slow down. The gravitational pull of the Sun on a comet causes the comet to change direction.
Forced Oscillations. In order to sustain oscillations in a simple harmonic system, a periodic force must be applied to replace the energy lost in damping. This periodic force does work on the resistive force decreasing the oscillations. It is sometimes known as an external driving force. These are known as forced oscillations (or vibrations ...
