Force
What is required to change the velocity of an object?
Force
If two soccer balls are at rest and then kicked, ball A moves 2 meters from its original spot and the ball B moves 4 meters from its original spot, which one received more force?
Ball B (4 meters)
A push or pull that can cause motion
Force
To start an object moving, the force must come from this direction:
any direction
What number of Newton's Law does this describe:
An object at rest stays at rest.
An object in motion stays in motion with the same speed and in the same direction UNLESS acted upon by an unbalanced force.
Newton's First Law of Motion
To stop an object, the force must come from this direction:
opposite
It takes more force to slow down your bicycle by 5 mph than to speed it up 5 mph. True or False
False
an increase in rate of change
acceleration
A pod hits a space station. The space station is much more massive than the pod. The pod experiences a much stronger force than the station. True/False
False
What number of Newton's Laws of Motion does this describe:
Every action has an equal and opposite reaction.
Newton's Third Law
To increase the speed of an object, the force must come from this direction:
the same direction
A pink canoe (200kg) and a green canoe (150kg) are crashed into from behind by giant rubber ducks. Both canoes increase their velocity by 3 km/sec. Which ones received MORE force from their rubber duck?
The Pink Canoe
Speed in a particular direction
Velocity
A pod hits a space station. The space station is much more massive than the pod. The pod experiences a much greater change in velocity. True/False
True
To push a more massive object farther and at the same speed as a lighter object, you have to ________ more force.
Exert
the tendency of something to stay in rest or motion
inertia
An object with less mass collides with an object with more mass. Which object will receive more force?
Neither
(both same amount of force)
Anything that has mass and takes up space
Matter
There is a collision between a bug and a car. The bug experiences a greater change in velocity because...
it has a smaller mass
Who would require less force to move 10 tiles across the floor in a chair with wheels: Hulk or Tinker Bell?
Tinker Bell
