Science

• Projectile motion - is the motion of a body or object thrown near the earths surface moving along a curve path due to the action of the gravity.
• object undergoing projectile motion is known as projectile
• The range(R) - is the horizontal distance reached by projectile from start to end.
• Trajectory - is the path fallowed of a projectile
• Maximum height - the highest vertical distance a projectile reaches
• Linear momentum - the objects tends to move in a straight line.
• Momentum also known as progress
• Impulse - a change of momentum brought about by the action of force on the object at a certain time
• Super elastic - kinetic energy is larger after the collision and objects separate
• Elastic - kinetic energy is conserve
• Inelastic - kinetic energy is smaller after the collision
• Completely inelastic - kinetic energy is smaller, and the objects stick together after the collision
• Momentum- an object is a product of mass and velocity
• Work- is done when a force is applied to a body
• Power- is defined as the rate of doing work
• Energy - capacity to do work
• The energy acquired by the object upon which work is done is known as mechanical energy
