Chapter 6 Newton's Laws "in class"

If you are given mass and force, how do you find acceleration?

• Multiply force and mass

• Divide mass by force

• Divide force by mass

• none of these

The Standard Unit for BOTH force and weight is the _____________. To calculate force using mass and acceleration, mass must be in units of ________ and acceleration must be in units of __________.

• Pounds, grams, m/s2

• Newtons, kilograms, m/s

• Newtons, grams, m/s2

• Newtons, kilograms, m/s2

Newton's 3rd law refers to what?

• The opposing forces that 2 objects have on one another

• The changing speed of an object and its mass

• The mass of an object compared to its acceleration

• A heavier object being harder to move

Newton's 2nd law refers to what?

• The lighter an object is, the easier it is to move

• The rate at which speed changes compared to the change in time and an objects weight

• The changing speed of an object and its mass

• Multiplying mass and speed to find force

Which of the following refers to Newton's 1st Law of motion?

• A larger applied force will require a large frictional force for equilibrium

• As an object speeds up, it will have less force.

• As an object slows down, it will have less force.

• When a vehicle goes around a curve, if its center of mass is too high, it will topple over

One word (sort of) for each of Newton's 3 laws "IN ORDER"

• inertia, Fma, action

• force, action, inertia

• mass, weight, force

• force, weight, mass

How would you find kilograms if given Newtons and m/s2?

• multiply Newtons and m/s2

• divide Newtons by 9.8

• divide m/s2 by Newtons

• divide Newtons by m/s2

In the cars with rubber bands and marbles lab, what could be a possible conclusion?

• Adding marbles adds force to the car.

• Adding more rubber bands made the car accelerate less.

• Adding marbles adds force to the car if friction is decreased.

• Adding more rubber bands increased the friction.

Which of the following is true regarding center of mass?

• It is always located below the middle for an object that is easy to knock over.

• It is lower for an object with a wide base.

• If 2 objects have the same mass, they will have the same center of mass.

• It is higher for an object with a wide base.

Which of the following accurately lists action/reaction pairs of forces?

• The marbles on the car and the car on the track.

• The marbles on the car and the rubber bands on the car.

• The car on the ramp, the car on the rubber bands.

• The car on the rubber bands, the rubber bands on the car.
