Name the two VERTICAL forces acting on the floating magnet.
GE and ME
GE and KE
GE and EE
GE and the vial
If a magnet is floating, the forces acting on the magnet must be equal and (a) .
The forces acting on the book to make it NOT move are:
1) static friction/AR
2) static friction/AR
3) GE
4) ???
(a)
The book on the table is not moving because the force between gravity and the table are (a) in magnitude (strength) and in opposite directions.
Which object, the sun or the Earth, has a greater gravitational pull?
the Earth
the sun
neither
both
The stick person pushes on a heavy box, but it does not move. The box will not move until an opposite force is (a) than the person's push.
The box has a stronger force than the person because the box has more m (a) .
When a ball moves down toward the ground, what forces are acting on the ball?
GE
EE
AR
GE, KE, and AR
When a ball moves on its way back up from the floor, what forces are acting on the ball?
EE and KE
EE, KE, GE
EE, KE, AR, and GE
GE
If you were walking through a magical forest and saw a person levitating and not moving, what could you conclude about the forces acting on the person?
The forces are equal.
The forces are opposite.
The forces are equal and opposite.
There are no forces.
A person puts on socks, runs, and slides across the floor. Which of the following is most likely to happen?
The speed of the person will be constant because their force from the slide is still there.
The speed of the person will be constant because there is no force involved.
The speed of the person will decrease because there is friction between them and the floor.
The speed of the person is zero because there is no force acting on the person.
Callie is shown in the picture sitting on the couch, not moving. Why is Callie not moving?
She is too heavy for other forces to be acting on her.
There are no forces acting on Callie.
Gravity is holding Callie to the couch.
The couch is pushing up on Callie with the same force that gravity pulls her down.
A cat and a box of packing foam have static electricity energy with each other. The cat is big and the packing foam is small. Will the cat have MORE or LESS static electricity energy than the foam?
(a)
