CONCEPT RECALL: It is the tendency of an object to persist in its state of rest or of uniform motion in a straight line.

CONCEPT RECALL: It is a type of force that requires physical contact between objects.

CONCEPT RECALL: It is a type of force that causes a change in motion and has a net force not equal to zero.

CONCEPT RECALL: Forces acting on an object at the same time are combined.

COMPREHENSION: You are to adjust to a new environment but you want to resist the changes because you are stable and steady in your position. What law is being exhibited by this situation?

COMPREHENSION: Five coins tied on a thread can be spun faster compared to several coins tied on a thread. What law is being exhibited by this situation?

COMPREHENSION: A man jumped off from a moving bus and tries to move towards the direction of the bus after landing. What law of motion can explain this occurrence?

COMPREHENSION: Swimming is possible by ‘slicing’ the water and pushing it with your hands. What law of motion can explain this occurrence?

COMPREHENSION: Zoey lines up to ride on the roller coaster zip line. As she was waiting in the line, she saw that her lighter classmates tend to sway a lot compared to those who have greater mass during the ride. Assuming that they were released on the line with the same amount of force, what law of motion can explain this?

DISCRIMINATION: Action-at-a-distance forces or field forces

DISCRIMINATION: Contact forces

DISCRIMINATION: Gravitational force

APPLICATION: A 10,000 kg-car experiences a 2,000-N horizontal net force. What could be its acceleration due to net force?

What formula will help you solve the problem?

APPLICATION: m = 10, 000 kg, F = 2000 N. What could be its acceleration due to net force?
