Back

Car 1

Front

What would most likely happen to the motion of the box if you poured oil on the ramp?

Back

It will speed up the box because the force of friction will be reduced.

Front

Did increasing the force on an object increase its speed?

Back

Yes, because more force reduced the time needed to travel 5 meters, so it was going faster.

How can you increase the acceleration of an object? Options: decrease its mass, increase its friction, increase its mass, decrease the force applied to it

Back

decrease its mass

Front

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes: Newton's first law, the law of inertia, Newton's second law, the law of acceleration, Newton's third law, the law of action reaction, The law of universal gravitation.

Back

Newton's second law, the law of acceleration
