which of the following is defined as a force working against your body that tends to slow you or an object down?
a energy
b friction
c velocity
d resistance

Explanation:

• For the first question, in a second - class lever, the weight is between the pivot point and the force, and it increases the force applied.
• For the second question, a sprinter needs acceleration to quickly take off at the start of a race.
• For the third question, resistance is a force that acts against an object or body and tends to slow it down.

Answer:

c. Second - class
a. Acceleration
d. Resistance
