Which is an example of a non-contact force?
Woman pulls open a door.
A magnet pulls an item toward it.
A student pushes his chair in at his desk.
A rolling ball slows down from friction.
Which picture shows balanced forces?
The picture shows a crane holding a crate in the air. Neither the crane in the air nor the crate is moving. Which set of arrows correctly illustrates the forces acting on the crate?
A student tries to push a refrigerator-sized box of textbooks safely across the classroom.
The box does not move. He asks for help from other students.
The box starts to move when the number of students shown in the image are pushing together. Based on this information, what conclusion can be drawn?
The box has a mass greater mass.
The forces acting on the box became unbalanced when the third student started pushing
When the third student started to push, the box’s mass decreased.
The only force acting on the box is the push applied by the students.
Nancy investigated force by applying different forces to the same object and measuring how far the object moved.
She recorded her observations in a table.
Which conclusion can be supported by the evidence shown in Nicole’s observation table?
Forces cannot be accurately measured.
Force has no effect on motion.
A greater force causes a greater change in motion.
Trials always give different measurements
Lisa is helping her family move. She tries to push a desk, but she can only move it very slowly.
She asks her brother to help, and they begin to push the desk together.
What happens to the movement of the desk and why?
The desk moves slower than it did before because more force is applied.
The desk moves faster than it did before because less force is applied.
The desk moves faster than it did before because more force is applied.
The desk moves slower than it did before because less force is applied.
Look at the path a golf ball travels once it is struck by a golf club.
In what order are forces acting on the ball?
gravity, push, friction
friction, gravity, pull
pull, push, gravity
push, gravity, friction
The person kicks the ball in the image below 20 meters. Suppose the soccer ball in the image is replaced by one that is twice the mass of a regular soccer ball. How could the person kick the ball the same distance as the first soccer ball?
kick the ball in a different direction
kick the ball with the other foot
kick the ball with less force
kick the ball with more force
A student measures how far a marble rolls across a table when the table has different coverings on it.
Then, the student puts the data into a table.Which is the best prediction for how far the marble will roll on the tablecloth for trial 3?
12 cm
7 cm
18 cm
22 cm
Jake conducted an investigation on how force affects the motion of an object. He asked three of his friends to throw the same rock straight up into the air with different amounts of force. He measured how long it took each rock to fall back down and hit the ground. The table shows his results. Which description of the force applied to the rocks is correct?
Kim applied more force to the rock than either Ted or Elias did.
Kim applied less force to the rock than either Ted or Elias did
Kim applied more force to the rock than Ted did and less force than Elias did.
Kim applied less force to the rock than Ted did and more force than Elias did.
