Mr. Bekius?
Doubtful
• Mr. Bekius climbed to the top of the Empire
State Building and dropped an quarter. He
watched it fall to the ground. Why does the
quarter fall to the ground?
A.) Mr. B has super powers
B.) mass
C.)acceleration
D.) gravity
• When Mr. Bekius lifts 4 cows at once, he is
using a contact force. Why is this an example
of a contact force?
A.) Mr. B’s muscles are bigger than the cows.
B.) The cows are moving.
C.) He is touching the cows to lift them.
D.) The cows changed position therefor they
are in motion.
• What three things are used to describe an
objects motion?
A.) resistance, force, time
B.) time, force, time
C.) friction, direction, resistance
D.) distance, time, direction
E.) all of the above
• Name an action that is caused by a noncontact
force.

a hill and gains speed. He then stops pushing
off the ground with his foot. What will cause
him to stop?
A.) air resistance
B.) friction
C.) gravity
D.) all of the above

B.) explode
C.) continue moving in the
same direction

• Give Mr. Bekius an example of a balanced
force.

muscle law
• A child and an adult are ice skating. The child
pushes away from the adult. The child moves
backward. What will happen to the adult?
• Use Newton’s first law of motion to explain
why it is safer to wear a seat belt in a moving
car.
• Use Newton’s second law of motion to explain
why kicking a bag of soccer balls across a field
takes more force than kicking one soccer ball
across a field.
• Two forces are acting on an object at rest.
How can you tell if the forces are balanced or
unbalanced?
