The motion of an object can be calculated once you know a few key bits of data, for example the distance travelled in a certain amount of time. There are plenty of new equations to use in this section, but you'll get there with practice.

A moving object has . This is the tendency of the object to keep moving in the same direction. It is difficult to change the direction of movement of an object with a lot of momentum.

Momentum can be calculated using this equation:

is the momentum in kilograms metres per second, kg m/s

For example, what is the momentum of a 5 kg object moving with a velocity of 2 m/s?

thrust - increases the velocity of an object

air resistance - decreases the velocity of an object

torque - changes the rotation of an object

The Thrust supersonic car (ThrustSSC) was the first car to break the sound barrier when it was driven at 763 miles per hour in 1997. It has huge thrust and is streamlined to minimise air resistance.

Isaac Newton was an English physicist and mathematician. He determined that gravity was a force that acts between two masses . The larger the masses, the larger the gravitational force between them.

Charles-Augustin de Coulomb was a French physicist. He first described the electrostatic force . This is a force that acts between two charges .
