A large moving ball collides with a small stationary ball. The momentum
of the large ball decreases, and the momentum of the small ball increases.
of the small ball decreases, and the momentum of the large ball increases.
of the large ball decreases, and the momentum of the small ball decreases.
does not change for either ball.
Many factors can affect what happens when balls collide. For example, the material the ball is made from, how hard the balls hit each other, whether both balls are moving, and the directions they are moving in.
If two tennis balls are moving towards each other at the same speed what do you expect to observe (see)?
Both balls stop moving
One tennis ball will stop and the other will keep moving
One tennis ball will jump over the other ball
Both balls bounce off each other
What happens when two objects collide?
Energy is changed into force.
Energy is transferred from one object to another.
Energy is created and the objects move faster.
What effects the amount of energy transferred in a collision?
the speed
the weight
the speed AND weight
While playing with toy cars, Kirsten and Luca each push a car toward the center of the room. What happens when the toy cars collide?
Energy is transferred.
Energy is unchanged.
As an object moves faster, it has more of what to transfer?
weight
density
energy
matter
What is transferred at the instant the bat hits the ball?
matter
energy
sound
light
To make a fair test or experiment you should change __________ variable(s) at a time.
one
two
three
four
Which of these is NOT true about energy?
it moves wind turbines
it knocks down bowling pins
it makes a baseball fly
you can hold it in your hand
What makes things happen?
matter
computers
energy
density
What happens when two objects collide?
Energy is changed into force.
Energy is transferred from one object to another.
Energy is created and the objects move faster.
(select all that apply) Which of the following concepts are used to analyze collisions?
forces
motion
acceleration
velocity
Which of the following is Newton's 1st law of motion?
an object at rest stays at rest and an object in motion stays in motion until acted upon by a force.
a force is an interaction between 2 objects
the force on an object is mathematically related to how fast and hard a mass hits it.
__________ is a measure of how much matter is in an object
mass
volume
weight
heaviness
Objects with more mass have more energy than objects with less mass. Therefore, If a heavy object is sitting still,
It will be easier to move becuase it takes less energy to move
It will be harder to move because it takes more energy to make it move.
A tennis player hits a tennis ball with his racket. Which of these is NOT likely to happen to the tennis ball after it is struck by the racket?
A. The ball could bounce off the racket and continue moving behind the tennis player.
B. The ball could stay with the racket.
C. The ball could pop straight up in the air.
D. The ball could move forward and away from the tennis player.

A. its position
B. its speed
C. its mass
D. its direction

A. The car stayed in the same position.
B. The car is moving backwards.
C. The car is in motion.
D. The car made a turn.
The fourth graders are playing kickball at PE. One student rolled a ball to a second student. As the ball rolls towards the second student, he kicks it. Which of these will change after the ball leaves his foot? Select all that apply.
A. position
B. speed

D. direction
A student crashed a blue cart into a block three different ways, all at fast speed. One time the cart had 0 washers, one time it had 4 washers and one time it had 8 washers. In which case was the force on the cart largest?
When the cart had 0 washers
When the cart had 4 washers
When the cart had 8 washers
It was always the same force
A student crashed a blue cart into a block three different ways, all at fast speed. One time the cart had 0 washers, one time it had 4 washers and one time it had 8 washers. In which case was the kinetic energy of the system the largest?
When there were 8 washers
When there were 4 washers
When there were 0 washers
They were all the same, mass does not affect energy
Which crash below transfers the most energy?
When a large football player and a smaller football player are running towards each other and crash
When two smaller football players are running towards each other and crash
When a smaller football player hands off the football to another football player
How much force is needed to cause permanent damage to a solid object?
Any nonzero force on a solid object will cause permanent damage
10N
Any force that bends the object beyond its elastic limit will cause permanent damage
In a collision between two objects
The objects bend
There are forces between the objects
Energy is transferred between the objects
All of the above
Which of the following are examples of collisions?
One pool ball striking another
A bat hitting a baseball
Fingers pressing keys on a piano
All of the above
When two or more objects exert forces on each other for a short period of time, it is called:
momentum
work
a collision
friction
What is acceleration?
It's the same as Velocity
It's the change of velocity (or speed or direction of an object)
What happens to the kinetic energy in a collision?
Some of it is transferred to the other object
Some is transformed into other forms (sound or thermal)
Nothing happens to it
