100
The tendency of an object to resist a change in its motion is known as this.
What is Inertia?
100
A baseball thrown into the air will continue on its path until which force acts upon it.
Friction
100
Speed of a car traveling 400m in 20 seconds.
What is 80m/s?
100
On this Distance vs. Time graph, the motion of the object between 4 seconds and 6 seconds.
What is no motion or at rest?
100
Moving parts in machinery are coated in oil and grease to reduce this.
What is Friction?
100
DAILY DOUBLE (DOUBLE POINTS)
The difference between normal force and applied force.
What is applied force is a force exerted on an object and normal force is the force supporting the object.
200
The law being demonstrated here. Explain.
What is all three?
200
This is the what gravity acts on to give an object its weight
What is Mass?
200
The acceleration of a 50kg object pushed with a 500N force.
What is 10m/s2?
200
The motion of the object between 5 seconds and 7 seconds.
What is constant speed?
200
What do simple machines do?
Help change direction or amount of force needed to move an object
200
The letters of the objects that are accelerating:
a. Walking at a constant speed going around a track
b. slowing down at a stoplight
c. speeding up after the light turns green
d. traveling 60mph down the highway
What are a, b, and c?
300
In absence of acceleration, a moving object has a constant this.
What is Speed?
300
DAILY DOUBLE!! ANSWER BOTH PARTS FOR DOUBLE POINTS!!!
A 20 kg ball and a 50 Kg ball rest at the top of a ramp. Which has greater Potential Energy? WHY?
50 KG - because it has the GREATER MASS!
300
The amount of time it takes to go 200 meters while walking 1.5m/s.
What is 133.3s?
300
The acceleration for the first 5 seconds.
What is 10m/s2?
300
Mechanical advantage of this inclined plane.
What is 3?
300
Type of friction between the dresser and the floor AND the best way to overcome the amount of friction.
What is static friction between the dresser and floor AND rolling friction to overcome the static friction?
400
The law primarily responsible for launching a rocket.
What is the 3rd law (action-reaction)?
400
A ball rolls on a carpet. The ball experience friction as it rolls. How will friction affect the ball´s motion?
The ball experiences an unbalanced force and will slow down
400
Final speed of a Ferrari with the initial velocity of 10m/s accelerating at 50m/s2 for 3 seconds.
What is 160m/s?
400
The acceleration between 7 and 8.5 seconds.
What is -33.3m/s2?
400
The mechanical advantage of this wheel and axle.
What is 6?
400
The acceleration of falling objects.
What is 9.8m/s2? (10m/s2)
500
Because of the 3rd law of motion... If both objects are thrown with the same force, which would move back further after they collided - a 145g baseball or a 45g golf ball
EXPLAIN WHY?
Golf ball - Because the smaller the mass - the greater the acceleration
500
A change in the gravitational force acting on an object is its this.
What is Weight?
500
The distance Tommy lifts his grocery bag using 25 N of force while doing 50J of work.
What is 2m?
500
Line segment(s) when the object is at rest.
What is CD?
500
The screw that has the higher mechanical advantage and why.
What is the screw on the right or the screw with the narrower pitch?
500
Difference between mass and weight.
What is mass is the amount of matter in an object and weight is the force of gravity pushing down on a mass?
