Work is when a force is used to move an object.
Which of these is an example of work?
Sitting at a desk.
Riding a bike.
Pushing on a wall.
Reading a book.
The gravity on the Moon is weaker than the gravity on Earth. Compared to the mass and weight of the astronaut on Earth, on Mars she has:
less mass and weight.
less mass but equal weight.
equal mass but less weight.
equal mass and weight.
Simone Biles tumbles across the floor with an acceleration of 3m/s2 striking the floor with a force of 141 N. What is her mass?
141N ÷ 3m/s2 = 47 kg
3m/s2 ÷ 141N = 0.02 kg
141N × 3m/s2 = 423 kg
What is the net force on the rope?
12 N
58 N
12 N + 58 N = 70 N
58 N - 12 N = 46 N
What is the net force on the ball?
5 N
9 N
5 N + 9 N = 14 N
9 N - 5 N = 4 N
If the man pushes with an equal amount of force, which object will accelerate more?
Car because it has more mass
Lawnmower because it has less mass
Car because it has less mass
Lawnmower because it has more mass
What does friction do to a moving object?
Makes it rise
Speeds it up
Slows it down
All choices are correct
If the van stops suddenly, what happens to the box on top if it is not tied down?
The box moves to the side.
The box stops with the van.
The box moves forward.
The box moves backwards.
On which planet would your mass be the greatest?
Earth
Jupiter
Sun
Your mass doesn't change.
Why does the ice in picture B make it easier to move the refrigerator and box?
The ice is smooth, which increases friction.
The ice is smooth, which decreases friction.
The ice makes the items weigh less.
The ice reduces the mass of the items.
What concept does this picture demonstrate?
For every action, there is an equal and opposite reaction.
The greater the force, the farther an object will move.
Unless an external force is applied to an object, it will tend to remain at rest.
What could be changed to make the results of this collision equal?
Make the characters move faster.
Make the characters move at the same speed.
Make the characters have the same mass.
What happens to the change in motion of each monster after the collision?
A small change for red.
A big change for blue.
A big change for red.
A small change for blue.
The motions of red and blue do not change.
A big change for red.
No change for blue.

The woman is more powerful if she does...
The same amount of work in more time.
The same amount of work in less time.
The same amount of work in any amount of time.
Andre and Tiffani both run the stairs for a workout. It takes Andre 20 minutes to complete his workout. Tiffani finishes the same workout in only 10 minutes. Tiffani has—
Half the power that Andre has.
Twice as much power as Andre.
Twice the work compared to Andre.
