changing ROLLING friction to SLIDING friction.

separating surfaces with a layer of air.

sanding rough surfaces smoother.

separating surfaces with a LUBRICANT.

Which statement about the ACCELERATION of an object is correct?

Directly proportional to the next EXTERNAL force, but inversely to its mass.

Directly proportional to its net EXTERNAL force & mass.

Inversely proportional to the net EXTERNAL force, but directly to its mass.

Inversely proportional to its net EXTERNAL force & mass.

Car pulled by Towing Cable In the diagram, the 5800 N force is:

the backward force the road exerts on the car.

the force exerted by the towing cable on the car.

the gravitational force acting on the car.

the upward force the road exerts on the car.

"F" accelerates a box from rest across a ROUGH horizontal surface, at a constant rate . The experiment is repeated, and all conditions remain the same with the exception that the horizontal force is doubled (x2) . What happens to the box's acceleration ?

It increases to MORE THAN double its original value .

It increases to EXACTLY double its original value .

It increases to LESS THAN double its original value .

Strange as it may seem, it is just as hard to accelerate a car on a level surface on the moon as it is here on the Earth.

This is because the mass of the car is independent of gravity.

Nonsense! This depends upon the phase of the moon .

This is because the weight of the car is independent of gravity.

Nonsense! A car is much more easily accelerated on the moon > Earth.

Weight, by definition, is:

the gravitational attraction force between you and the Earth.

a property of mechanical equilibrium.

According to Newton's 2nd law... When the SAME force is applied to TWO (2) objects of different masses ...

The object with GREATER mass will experience SMALLER acceleration The object with LESS mass will experience GREATER acceleration

The object with GREATER mass will experience SMALL acceleration The object with LESS mass will experience EVEN SMALLER acceleration

The object with GREATER mass will experience GREATER acceleration The object with LESS mass will experience an EVEN GREATER acceleration

The object with GREATER mass will experience GREATER acceleration The object with LESS mass will experience SMALLER acceleration

A large mass M and a small mass m are dropped from a great height. Which statement about their terminal velocities is correct?

Larger mass = Larger terminal velocity Due to larger air resistance and thus, a larger speed being required to balance its larger weight.

BOTH masses will reach the same terminal velocity According to Newton's 3rd Law.

Both masses will reach the same terminal velocity, Due to all the fact that all masses fall at the same speed , according to Galileo.

Smaller mass = Larger terminal velocity Due to encountering less air resistance, allowing it to speed up more quickly.

If no external forces are acting on a MOVING OBJECT, it will . . .

continue moving at the same velocity .

move slower and slower until it finally stops.

continue moving at the same speed .

A single force acts on an object. The components of this force act along the + x -axis and the - y -axis. The single force that will bring the object into equilibrium has components that act along the...

Negative X-Axis and Positive Y-Axis

Negative X-Axis and Negative Y-Axis

Positive X-Axis and Negative Y-Axis

Positive X-Axis and Positive Y-Axis

According to Newton's Law of Inertia (1st Law)... A railroad train in motion should continue going forever even if its engine is turned off . We NEVER observe this because railroad trains:

always have forces that oppose their motion.

Newton's third (3rd) law of motion involves the interactions of:

two (2) objects and two (2) forces.

one (1) object and one (1) force.

one (1) object and two (2) forces.

two (2) objects and one (1) force

A hammer drives a nail into a piece of wood. Identify an action-reaction pair in this situation.

Hammer EXERTS FORCE on nail ; nail EXERTS FORCE on hammer .

Hammer EXERTS FORCE on nail & wood

Hammer EXERTS FORCE on nail ; wood EXERTS FORCE on nail .

Nail EXERTS FORCE on hammer ; hammer EXERTS FORCE on wood .

Whirl a rock at the end of a string and it follows a circular path. If the string breaks, the tendency of the rock is to:

continue to follow a circular path.

A hockey stick hits a puck on the ice. Identify an action-reaction pair in this situation.

Stick EXERTS FORCE on puck ; puck EXERTS FORCE on stick .

Stick EXERTS FORCE on puck ; puck EXERTS FORCE on ice .

Stick EXERTS FORCE on ice ; ice EXERTS FORCE on puck .

Puck EXERTS FORCE on stick ; stick EXERTS FORCE on ice .

A falling object's "Tv" is reached when the force of gravity...

is EQUAL to the force of air resistance.

is the ONLY force acting on the object.

is GREATER THAN the force of air resistance.

is LESS THAN the force of air resistance.

As an object falls toward Earth :

the UPWARD acceleration of Earth is NEGLIEBLE because of its large mass .

the object exerts a DOWNWARD force on Earth.

Newton's third law does not apply .

the object does not exert a force on Earth.

You are pushing a rock along level ground and making the rock speed up . How does the size of the force you exert on the rock compare with the size of the force the rock exerts on you ? The force you exert

is the SAME SIZE as the force the rock exerts on you.

is SMALLER than the force the rock exerts on you.

could be any of the above; it depends on other factors.

is LARGER than the force the rock exerts on you.

A car goes forward along a level road at constant velocity . The ADDITIONAL FORCE needed to bring the car into equilibrium is:

"F" times the coefficient of kinetic friction

EQUAL TO (=) than "F" times the coefficient of static friction

GREATER THAN (>)"F" times the coefficient of static friction

When a rocket ship accelerating in outer space runs out of fuel , it:

accelerates for a short time , then slows down to a constant velocity .

accelerates for a short time , slows down , and eventually stops.
