Force...in ya to learn! :)

What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Why is it harder for the boy in Image B to get down the hill?

• Motion
• Friction
• Work
• Displacement

When you type on the keys of your Chromebook you are using a

• pull
• push
• gravity
• friction

_____ is the force that slows and stops motion between touching objects.

• Friction
• Gravity
• Pull
• Push

Why is there less friction between two ice cubes touching than between sandpaper on wood?

• They have rough surfaces.
• They have loud surfaces.
• They have smooth surfaces.
• They have bright surfaces.

Students test how friction affects the speed of a radio-controlled car. They create three tracks of the same length with different surfaces on each. The time it takes for the car to travel to the end of the track is recorded and shown below:

What can be concluded from these results?

• The more friction on the track, the more time it takes to

  reach the end.

• The less friction on the track, the more time it takes to

  reach the end.

• Friction does not affect the speed of the car.

• Friction does not affect the speed of the car.

A soccer ball is sitting loose in the moving wagon pictured below. If the wagon stops suddenly, the ball will—

• Stop immediately with the wagon

• Roll forward in the wagon

• Roll backward in the wagon

• Stay exactly where it is

A student performed an experiment in which he rolled a toy car across five different surfaces. He recorded the results on the chart above. According to those results, which surface had the LEAST amount of friction with the car tires?

• glass

• sand

• grass

• pebbles

A pencil falls off a desk. What pulls the pencil toward the floor?

• magnetism

• potential energy

• kinetic energy

• gravity

How is gravity affected by mass?

• the larger the mass of the object, the greater the gravity
• small objects have no gravity
• gravity is not affected by mass of objects, whether large or small
