Question 1: balanced forces

Answer:

When the total forces acting on an object are equal and opposite in direction. When forces are balances, no change in motion occurs.

Question 2: unbalanced force

Answer:

a force that is unequal in size and is in the same direction as the motion of the object. When forces are unbalanced, there is a change in motion.

Question 3: average speed

Answer:

the total distance traveled in the total amount of time it took to travel that distance; total distance/total time

Question 4: force

Answer:

a push or pull.

Question 5: constant speed

Answer:

when the speed of an object does not change throughout its time in motion.

Question 6: gravity

Answer:

the force of attraction between objects. The larger the object the greater its gravitational pull.

Question 7: friction

Answer:

a force that acts in the opposite direction of motion.

Question 8: instantaneous speed

Answer:

speed at any given point.

Question 9: motion

Answer:

a change in position compared to a reference point

Question 10: velocity

Answer:

the speed and direction of an object.

Question 11: frame of reference (reference point)

Answer:

an object in motion has to be compared to a non-moving object

Question 12: acceleration

Answer:

rate of change in velocity; when an object changes its speed, direction, or both.

Question 13: speed

Answer:

the rate of motion of an object. It's calculated by dividing the distance traveled by the time
