Unit03-Newton'sLowsOfMotion

What does it mean when all the forces acting on an object add up to zero?

• The object is accelerating.

• The forces are balanced.

• The object is moving in a circle.

• The forces are unbalanced.

What is the term used when all forces acting on an object are added together and the result is any force, regardless of its size or direction?

• Net force

• Balanced force

• Resultant force

• Equilibrium force

In the context of forces, what does it mean when the forces are unbalanced?

• The object remains stationary

• The object moves in the direction of the resultant force

• The forces cancel each other out

• The object moves in the opposite direction of the resultant force

What does it mean when forces are said to be balanced?

• The forces are all acting in the same direction.

• The net force acting on an object is zero.

• The forces are all of equal magnitude.

• The forces are acting in opposite directions.

If 1,000 different forces act on a physics student and they experience no force, what can be concluded about these forces?

• The forces are unbalanced.

• The forces are all equal.

• The forces are balanced.

• The forces are acting in the same direction.

According to Newton's 1st Law, what will happen to an object at rest if no unbalanced force acts on it?

• It will start moving

• It will stay at rest

• It will change direction

• It will accelerate

What does inertia refer to in physics?

• An object's ability to move faster

• An object's resistance to a change in speed and/or direction

• An object's tendency to fall

• An object's gravitational pull

What does Newton's 2nd law imply about an object that is accelerating?

• There is no force acting on it.

• There must be a force acting on it.

• It is moving at a constant speed.

• It is at rest.
