1
Which type of force must be applied in order to change an object's motion?
Unbalanced Force
Frictional Force
Balanced Force
Gravitational Force
2
According to Newton's Law of Action-Reaction a book pushes down on a shelf and -
The floor pushes up on the shelf
The book pushes on adjacent books
The shelf pushes up on the book
3
Which would require the greatest force to accelerate?
Dump truck
Cop car
Bicycle
Motorcycle
4
Which of the following is the best example of velocity?
Birds migrate south at 12 mph
A car travels 20 mph
A dog runs 3 mph for 1 hour
A basketball rolls 13 feet
5
Which of the following is the best example of acceleration?
A car travels at a constant speed of 30 km/h
A cat walks 103 yards
A truck slows to a stop
A book sits on a table
6
To calculate the net force acting upon on object you should use this formula:
f = m - a
f = m + a
f = m/a
f = ma
7
When you kick a soccer ball, your foot exerts a force on the ball and the ball -
Exerts an equal force back on your foot
Exerts a greater force back on your foot
Exerts a smaller force back on your foot
8
What is the tendency of an object to resist changes in its motion?
Acceleration
Velocity
Inertia
Friction
9
How do you calculate acceleration of a 25 kg object when 40 N of force are applied?
A = 40 N/25 kg
A = 40 N x 25 kg
A = 25 kg + 40 N
A = 25 kg/40 N
10
When a force is applied to an object, that object will apply a force in return that is -
equal and in the opposite direction
unequal and in the opposite direction
unequal and in the same direction
equal and in the same direction
11
Objects with smaller masses require _________ to accelerate than those with larger masses.
The same force
More force
Less force
12
If an object is at rest it will remain at rest until -
Gravity quits acting upon the Earth
An unbalanced force is applied
Balanced forces are applied
