What is FRICTION?
a push or a pull that can change the motion of an object
a force between an object and the surface it is moving over (always the opposite direction of motion)
the energy that an object has because it is moving
Sandra pushed a wooden block and it slid across the floor. The wooden block gradually slowed down and stopped after moving 10 meters. Why did the block stop moving?
The floor exerted a force that is opposite to the direction of the block’s motion. (friction)
The block ran out of force.
The purple and white balls sped up by 4 m/s. The green ball slowed down by 6 m/s. Which ball was hit with the strongest force?
White
Purple
Green
All the skiers were hit with a force. The red skier slowed down by 6 /ms, while the yellow and purple skiers sped up by 6 m/s. Which skier(s) was hit with the strongest force?
Red
Yellow & Purple
All the skiers were hit with the same amount of force because their velocity changed the same amount.
Which object was pushed with a stronger force?
A
B
They were pushed with an equal force.
True/ False: To cause an object to SLOW its velocity, you would exert a SMALL force in the opposite direction.
TRUE
FALSE
True/ False: To make an object CHANGE DIRECTION, the object needs to be hit with a MEDIUM sized force in the opposite direction.
True
False
True/ False: To make an object STOP MOVING, an object must be hit with a REALLY BIG force in the opposite direction.
True
False
The GREATER the FORCE, the __________________the velocity change.
BIGGER
SMALLER
Can an object ever run out of force and stop moving?
Yes, it happens all the time!
No, the only thing that makes an object slow or stop is a force in the opposite direction.
