acceleration
speed
inertia
question 18
1 pts
if an object is moving at a constant velocity, it means that
no net force is acting on it
a constant force is acting on it in the direction of its motion
a constant force is acting on it in the opposite direction of its motion
several forces are acting on it, but one force is greater than the others

Explanation:

• For Question 17: Motion is defined as a change in an object's position. Acceleration is the rate of change of velocity. Speed is a measure of how fast an object is moving. Inertia is the tendency of an object to resist changes in its state of motion.
• For Question 18: According to Newton's first law of motion, an object will remain at rest or in uniform motion (constant velocity) unless acted upon by a net external force. If an object is moving at a constant velocity, the net force acting on it is zero. A constant force in the direction of motion would cause acceleration (increase in velocity). A constant force in the opposite direction would cause deceleration (decrease in velocity). If one force is greater than others, there is a net force and thus acceleration.

Answer:

Question 17: motion
Question 18: no net force is acting on it
