Total questions: 10
Worksheet time: 8mins
The forces acting on an object can either be balanced or unbalanced. If an unbalanced force is applied to an object, what might happen to the object?
Only the speed of the object might change
Only the direction of the object might change
Both the speed and direction of the object might change
Neither the speed or direction of the object might change
Rina’s mother asked her to help move some items from the hall closet to the garage. One item she wanted to move was a large box of old school books. Rina tried to lift the box, but could not pick it up. What force was Rina NOT able to overcome?
frictional force
electrical force
gravitational force
magnetic force
The graph plots the distance in kilometers traveled by an object over time in hours. What can you conclude from this graph?
The speed of the moving object remains constant.
The speed of the moving object increases over time.
The speed of the moving object decreases over time.
The speed of the moving object first increases and then decreases.
On a recent trip to the grocery store, Robert recorded the speed of the car every minute and then created the graph below. Look closely at the graph below which plots speed versus time. Which labeled line(s) on the graph represent periods of time when the car was moving at a constant speed?
A, B, C, and E
A, C, and E
B and D
only E
Look at the illustration below of a block sitting on a table-top. The magnified view illustrates a force that exists between the two objects. Which type of force is demonstrated in the magnified view?
electrical force
frictional force
magnetic force
no force
The image shows the cars of a roller coaster racing down the track. How does the Law of Conservation of Energy BEST explain the energy of the cars on the track?
The kinetic energy of the cars is being transformed into potential energy.
The cars have potential energy, but no kinetic energy.
The potential energy of the cars is being transformed into kinetic energy.
The cars have kinetic energy, but no potential energy.
The illustration shows what happened when a balloon touched a girl’s hair. Which type of force caused the girl’s hair to cling to the balloon?
gravitational force
electrical force
magnetic force
frictional force
Marissa wants to know which of four routes that she could possibly take on her walk to school is the fastest. Which of the following is the BEST way for Marissa to gather information to answer this question?
She should look on a map to see which route looks shortest.
She should walk each route herself at a normal pace and time how long each takes.
She should take a survey of her friends to find out what they think is the fastest route.
She should have four friends each take one route and observe who arrives at school first.
Sam developed the following hypothesis for his science project: The speed of a skateboard rolling downhill is greater on steep hills than on flatter hills. How can Sam BEST test this hypothesis?
Push the skateboard with varying force down inclines set at different angles, and measure the force with which the skateboard hits the wall.
Push the skateboard with varying force down inclines set at different angles and measure the distance traveled each time.
Roll the skateboard down a single incline, and measure the force with which it hits the wall.
Roll the skateboard down inclines set at different angles, and measure the time it takes to roll the same distance each time.
A high-speed collision between two vehicles causes more damage than a low-speed collision. What is the reason for this?
Vehicles traveling at a high speed have no potential energy.
Vehicles traveling at a low speed have no potential energy.
Vehicles traveling at a high speed have more kinetic energy than vehicles traveling at lower speeds.
Vehicles traveling at a low speed have more kinetic energy than vehicles traveling at higher speeds.
