Investigate the motion of a projectile.

The "Reset" button brings the projectile to its initial position. You can start or stop and continue the simulation with the other two buttons. If you choose the option "Slow motion", the movement will be ten times slower. You can vary (within certain limits) the values of initial height, initial speed, angle of inclination, mass and gravitational acceleration. The radio buttons give the possibility to select one of five physical sizes.

The effect of air resistance is neglected.

## Glossary

### acceleration

the rate of change of velocity with time. It is a vector quantity with magnitude and direction.

### air resistance

This force caused by atoms and molecules in the air colliding with an object moving through the air acts in the opposite direction to motion. The larger the surface area of an object, perpendicular to its direction of motion, the more air will collide with it as it moves and so the greater the air resistance force. Normally in Mechanics it is generally assumed that the force of air resistance is small enough to be ignored.

### mass

a measure of the quantity of matter in an object

### projectile

a body moving in a gravitational field under free fall

### resistance

a force that opposes the motion of a particle. Its direction is always opposite to the direction of motion.

### speed

velocity without direction; a scalar quantity
