• Pulling the table with a rope at a low angle.

Isabella, Angel, and Tresia went rock climbing on a steep cliff. They used ropes and special climbing shoes to help them climb. Which force primarily prevents them from falling?

• Gravity

• Friction

• Magnetic

• Electric

When biking on a gravel path compared to a smooth road, how does friction primarily affect your speed?

• Friction is greater on gravel, making it harder to maintain speed.

• Friction has no effect on biking speed.

• Friction is lesser on gravel, allowing for faster speeds.

• Friction is greater on gravel, making it easier to pedal.

The Division of El Salvador City conducted a Boy Scout Camping; the said activity was attended by the learners from Grades 4 to 6 coming from different schools in the Division and they were divided into patrol teams. Each patrol teams were tested on how they will use their survival skills by cooking food without using matchsticks and LPG. They used variety of techniques on how they can produce a fire. Patrol Team A used two bamboo sticks to make a fire by rubbing them. What kind of energy transformation occurs when rubbing two bamboo sticks together?

• Nuclear Energy-Heat Energy

• Mechanical Energy-Light Energy

• Sound Energy-Mechanical Energy

• Mechanical Energy-Heat Energy

According to holiday weather.com, the month of March marks the transition from the cool dry season to hot dry season in the Philippines. She turns on the electric fan by plugging in the wire into the socket. What kind of energy transformation takes place when Mary Fe plugged the socket and turn on the electric fan?

• Electrical Energy to Mechanical Energy

• Chemical Energy to Electrical Energy

• Mechanical Energy to Electrical Energy

• Radiant Energy to Electrical Energy

The Grade 8 learners were tasked by their science teacher to do a group report. The class was divided into groups of 5 members each. Reazy’s group was tasked to report about energy transformation.
