This cart also had a rod to assist in readings. What is its volume at s.t.p.? The conservation of the energy is happening in the presence of conservative forces like gravitational forces or the _____________. This increase can be explained by the fact that the potential energy of the spring, that was holding the plunger back, was transferred to kinetic energy as the plunger was released. Momentum (, ) can be calculated by multiplying mass (, To begin the lab a Vernier Dynamic Track was set up and leveled on a table. %PDF-1.6 % If students have difficulties differentiating the characteristics associated with covalent and ionic bonding, they will suffer with future topics and other branches of chemistry. Add water to the cup until the total mass reads 200 g. Repeat A 50 kg ball traveling at 20 m/s would have kinetic energy.
