science

• Horizontal Motion. If there is no force acting on an object, then it will continue moving at a constant speed in
• Changes due to gravity, does Not cover equal displacements in equal time periods.
• Angle of release. In terms of height, for projectiles launched at a constant initial velocity, the steeped the angles is the greater is its maximum height.
• Momentum: the quantity of motion of a moving body, measured as a product of its mass and velocity.
• Impulse : change in the object's momentum as a result of a force acting on it
• collision: an instance of one moving object or person striking violently against another
• elastic collision: colliding object do not stick together. the final kinetic energy is the same as the initial kinetic energy
• Perfectly inelastic collision: colliding objects stick together. Final kinetic energy is less than the kinetic energy. momentum is conserved.
• Inelastic Collision: colliding object do not stick together. commonly result to deformation or generation of heat light or sound. Final kinetic energy is always less than initial kinetic energy.
• Potential Energy is energy that is stored in an object but not being used.
• Kinetic energy: The energy of an object due to its motion.
• Energy: The ability to do work or to do work against resistance.
• what is the 2 types of energy? Potential and kinetic energy
• Gravitational Potential energy:
• MASS: The greater the mass of an object, the greater the force of gravity acting on it.
• HEIGHT: The higher up an object is from the ground, the more gravitational potential energy it has.
• the 2 types of potential energy: gravitational potential energy and elastic potential energy
• Mechanical energy is the energy stored in a system due to the movement of objects.
