What happens to an object's acceleration as mass of the object increases?

it decreases as long as Force is the same

it increases as long as FORCE is the same

it decreases as long as the TEMPERATURE is the same

it increases as long as the TEMPERATURE is the same

If two forces act on an object in the same direction, the net force is the _____________

the difference between the two forces

Only one of the forces acts on the object

The multiplication of both forces

A force that resists the motion of two surfaces sliding across one another.

A push or pull that causes an object to move, stop, or change direction.direction.

A change in position or location

The force that causes objects with mass to attract one another.

What is happening at D?

Fast steady speed; moving away from the starting position

Slower steady speed; moving away from the starting position

Which of the following is NOT an example of acceleration?

A car traveling at a steady speed of 20 km/hr

A runner sprinting at a rate of 10 m/s and then slowing down at the finish line

The dot-car traveling down a ramp

Acceleration is defined as the CHANGE in

velocity divided by the time interval

time it takes for one place to move to another place.

distance divided by the time interval

Two cars with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time to stop?

The car with the smaller mass will require less force to stop than the car with the larger mass.

The car with the larger mass will maintain its velocity while traveling down the hill.

The car with the smaller mass will take longer to stop than the car with the larger mass

The car with the larger mass will have less inertia than the car with the smaller mass

Consider the two examples below. In which instance is more work done?

Example A and Example B represent the same amount of work.

Neither example represents any work done.

Which of these best explains why the coin fell straight down into the cup instead of remaining on the index card?

The coin was at rest until the card was removed, so it tended to remain in the same location. Once the card was gone, the unbalanced force of gravity caused the coin to fall.

Moving the card applied an action force on the coin. Since the card was gone, gravity applied a reaction force on the coin.

The card had less mass than the coin, so a smaller force of gravity acted on the card. The larger force of gravity on the coin made it fall.

The acceleration of the coin falling into the cup was equal and opposite to the acceleration of the card.

How could you reduce the amount of friction on the box the man is pushing?

replace sliding friction for rolling friction

How could you increase the fuel efficiency of your vehicle?

Remove unnecessary items to reduce weight

Load the trunk with heavy weights to increase friction

A student uses the same force to throw a ping pong ball, and a bowling ball. Which statement is true.

The ping pong ball will move farther than the bowling ball

The ping pong ball and bowling ball will go the same distance

The bowling ball will move farther than the ping pong ball

Why would you weigh more on Earth than on the moon?

none of the above-mass doesn't matter
