Force and Motion

What is rolling friction?

• The friction that occurs when an object slides over a surface.

• The friction that occurs when an object rolls over a surface.

• The friction that occurs when an object is at rest on a surface.

• The friction that occurs when an object is thrown through the air.

What is the relationship between force and motion?

• A force can cause an object to start moving, stop moving, or change direction.

• Force is unrelated to the motion of an object.

• Motion can occur without any force acting on an object.

• Force only affects the speed of an object, not its direction.

What is inertia?

• The tendency of an object to resist changes in its state of motion.

• The force that causes an object to accelerate.

• The speed of an object in a given direction.

• The mass of an object multiplied by its velocity.

What happens to a moving object when no net force acts on it?

• It comes to a stop immediately.

• It continues to move at a constant velocity.

• It accelerates in the direction of motion.

• It changes direction randomly.

What is the effect of an outside force on a moving object?

• It can change the object's speed or direction.

• It has no effect on the object's motion.

• It can only increase the object's speed.

• It can only change the object's color.

What is sliding friction?

• The friction that occurs when two surfaces slide against each other.

• The friction that prevents surfaces from sliding against each other.

• The friction that occurs when an object is at rest on a surface.

• The friction that occurs only in liquids.

What is acceleration?

• The rate of change of velocity of an object.

• The speed of an object in a straight line.

• The force applied to an object.

• The distance traveled by an object over time.

What is speed?

• The distance traveled per unit of time.

• The total time taken to travel a distance.

• The rate of acceleration of an object.

• The maximum distance an object can travel.

What is fluid friction?

• The resistance encountered by an object moving through a fluid (liquid or gas).

• The force that opposes the motion of an object on a solid surface.

• The friction that occurs between two solid objects in contact.

• The resistance faced by an object moving through a vacuum.

What is motion?

• The change in position of an object over time.

• The speed of an object at a given moment.

• The force applied to an object to move it.

• The distance traveled by an object in a straight line.
