Total questions: 30
Worksheet time: 20mins
In order for an object to speed up, the direction of the force is:
in any direction
in the same direction as the object's motion
in the opposite direction of the object's motion
In order for an object to start moving, the force must come from
the same direction as the object's motion
the opposite direction as the object's motion
any direction
In order for an object to stop moving, the force must come from
the same direction as the object's motion
the opposite direction as the object's motion
any direction.
A push or pull that can cause motion.
velocity
speed
cause
force
Speed in a particular direction
force
velocity
motion
Which of the following pictures models Claim 1: The thrusters caused the pod to move in the opposite direction.
Which of the following models claim 2: The thrusters only slowed the pod, it didn't stop. The pod hit the space station, which made it bounce and move in the opposite direction.
How are speed and velocity different?
Speed includes direction
Speed indicates momentum
Velocity includes Momentum
Velocity includes direction
_____ is the force that slows motion between touching objects.
Friction
Gravity
Pull
Push
The motion of an object depends on the_____ of the object and the amount of ____ used.
outside and equal
mass and force
force and Sir Isaac Newton
An event or process that leads to a result or change
Exert
Change
Force
Cause
Speed is
speed in a particular direction
how fast an object is moving
the moment when two objects hit each other
a force between an object and the surface it is moving over
The moment when two objects hit each other
Force
Speed
Collision
A ___________ is required to change the velocity of an object.
force
larger mass
smaller mass
A stronger force can cause a greater change in
direction.
speed.
velocity.
mass.
How many ways can an object change motion?
2
6
3
5
The amount of matter in an object is called its...
pressure
weight
mass
force
Which happens first: cause or effect?
Cause
Effect
If the same strength force is exerted on two objects, the object with ________ mass will have a _________ change in velocity.
less, smaller
more, greater
more, smaller
less, shorter
Which of the following is NOT TRUE about friction:
Friction is a force that acts in the opposite direction of motion.
Friction slows objects down.
There is no friction on earth.
Friction on carpet is greater than friction on a bare floor.
Three boats were moving across the surface of a lake. The gray and pink boats are a greater mass than the orange boat. Each boat was bumped by another boat. Which boat experienced the strongest force when hit? How do you know?
The gray and pink boats because they are more massive, and all boats changed velocity by same amount.
The pink boat - it's as massive as the gray boat and has the highest ending speed.
All three - they all changed speed by the same amount.
The gray boat - it takes more force to slow down an object than it takes to make it go faster.
In which crash did the puck experience a stronger force?
The puck didn't experience a force. Only the paddles experienced force.
Crash 2: The force of the purple paddle was stronger in this crash because it has more mass, so the force on the puck was stronger,
The diagram doesn't tell you anything about the force on the puck.
The puck experienced the same force in both crashes.
In which crash did the test car experience a stronger force?
Crash 1: Force on garbage truck was stronger, so force on car was also stronger.
There is NO force on the car. In each crash, only the truck experienced force.
It was the same from both crashes. The trucks changed speed by the same amount in both crashes, so the force on the test car was the same both times.
The diagram doesn't tell you anything about the force on the test car. It only tells you about the force on the trucks.
In which crash did the rubber duck experience a stronger force? How do you know?
There is no force on the rubber duck. One the toy boats experienced a force in those crashes.
The diagram doesn't tell you anything about the force on the rubber duck.
The force was the same in both crashes.
Crash two because the force on the orange boat is stronger.
In which crash did the skateboard experience the stronger force? Why?
The skateboard did not experience force, only the shopping cart did.
Crash 2; the force on the cart was stronger in this crash.
The diagram doesn't tell you anything about the force on the skateboard.
The skateboard experienced THE SAME force in both crashes.
In which crash did the tennis ball experience a stronger force?
Crash 1: The force on the soccer ball was strong so the force on the tennis ball was also stronger.
There was NO force on the tennis ball.
The force was the same in both crashes.
The diagram doesn't tell you anything about the force on the tennis ball.
In which crash does the satellite experience a stronger force?
It was the same force in both crashes.
Crash 1: The force exerted by the black asteroid would have been stronger in this crash, so the force on the satellite would also have been stronger.
The diagram doesn't tell you anything about the force on the satellite.
There is no force on the satellite.
In which crash did the asteroid experience the stronger force?
There was no force on the asteroid.
Crash 2: The force on the planet was stronger in this crash. So the force on the asteroid was stronger.
The diagram doesn't tell you anything about the force.
The force was the same in both crashes.
