contact force, net force, balanced force
non-contact force, net force, unbalanced force
balanced force, unbalanced force, net force

Which of the following statements is NOT true about what forces can do to an object?
causes an object to STOP from moving
causes an object at rest to START MOVING (it can speed up or slow down the object)
causes an object to CHANGE ITS DIRECTION
causes a moving object to CONTINUE MOVING
Why do you think space crafts are able to move up into space without falling back?
Because it is heavier than the gravity.
Because it has wings to fly.
Because it has a machine that moves with a rapid speed.
Because the ground pushes it upwards.
A ball rolls down from the top of a grassy hill, reaches the bottom of the hill, continues to roll, and then starts to slow down and comes to a stop. What forces caused this ball's motion?
Frictional force caused the ball to roll down the hill, but air resistance caused the ball to slow down and stop.
Magnetic force caused the ball to roll down the hill, but gravity caused the ball to slow down and stop.
The force of the hill caused the ball to roll down it, but gravity caused the ball to slow down and stop.
Gravity caused the ball to roll down the hill, but frictional force caused the ball to slow down and stop.
When we stand on a surface, the force of gravity is opposed by the reaction force, also known as the
frictional force
normal force
tension force
applied force
A force that is applied to an object either it was done by a person or another object.
Applied Force
Friction Force
Tension Force
Normal Force
A force that is passed thru strings, ropes, cables, wires when they are being pulled apart by opposing forces.
Applied Force
Friction Force
Tension Force
Normal Force
Which of these involves a contact force?
A planet in orbit around a star
A skydiver falling through the air
Electrons attracted to the nucleus of an atom
Which of the following objects will experience an unbalanced force?
A bike rider on a smooth and level road, pedaling at a constant rate.
A train pulling on another train, each with the same amount of force.
A chair sitting on the floor with balanced forces acting in opposite directions.
A ball rolling across the floor with friction acting in the opposite direction.
