Question

what definition of force does the video give? * 10 points
a. a change in an objects temperature
b. any kind of push or pull on an object
c. the speed of an object in a given direction
d. the mass of an object
according to the video, what causes an object to start moving? * 10 points
a. balanced forces
b. unbalanced forces
c. constant velocity
d. equal mass on both sides
newtons third law is described in the video. which example matches that * 10 points
law?
a. a ball stays still on the table because forces are balanced
b. when the ball hits an opponent, the opponent exerts an equal and opposite force
back on the ball
c. a heavier ball always travels faster than a lighter ball when thrown with the same
force
d. velocity and acceleration are the same thing

Explanation:

• For the first question, force is defined as any kind of push or pull on an object.
• For the second question, unbalanced forces cause an object to start moving.
• For the third question, Newton's third law states that for every action, there is an equal and opposite reaction. When the ball hits an opponent, the opponent exerts an equal and opposite force back on the ball, which matches this law.

Answer:

1. B. Any kind of push or pull on an object
2. B. Unbalanced forces
3. B. When the ball hits an opponent, the opponent exerts an equal and opposite force back on the ball
