An object at rest remains at rest. An object in motion remains in motion unless acted upon by an outside force. This describes which of Newton's Laws of Motion? (1 point)

Question

• Second and Third Laws of Motion
• Second Law of Motion
• First and Third Laws of Motion
• First Law of Motion

Answer 1

This describes the First Law of Motion.

Answer 2

Suppose 25 children who weigh the same are playing a game of tug-of-war. Five children pull with 10 newtons of force, while ten children pull with 15 newtons of force in the opposite direction. How can one determine the net force on the rope? (1 point)
• The forces are in opposite directions, so the newtons can be divided.
The newtons are in the same direction, so the newtons can be multiplied.
The forces are in opposite directions, so the newtons can be subtracted.
• The forces are in the same direction, so the newtons can be added.

Answer 3

The correct choice is: The forces are in opposite directions, so the newtons can be subtracted.

Answer 4

To measure average speed, what data is required? (1 point)
• The direction of travel and the weight of the bike
• The weight of the bike and the time spent
• The distance traveled and the time spent
• The direction and the distance of travel

Answer 5

To measure average speed, the required data is: The distance traveled and the time spent.

Answer 6

Which example shows an object acted on by two balanced forces?
(1 point)
• A baseball rolling to a stop
• A car moving at a constant speed in a constant direction
• A snowflake landing on a roof
• A skateboard rolling down a hill with increasing speed

Answer 7

The example that shows an object acted on by two balanced forces is: A car moving at a constant speed in a constant direction.

Answer 8

Speed, unlike acceleration or velocity, does NOT specify (1 point)
• Distance
) Mass
• Time
• Direction

Answer 9

Speed, unlike acceleration or velocity, does NOT specify: Direction.
