1
What is the tendency of an object to resist changes in its motion?
Acceleration
Velocity
Inertia
Friction
2
Which of the following is the best example of acceleration?
A car travels at a constant speed of 30 km/h
A truck slows to a stop
A book sits on a table
A cat walks 103 yards
3
When you kick a soccer ball, your foot exerts a force on the ball and the ball -
Exerts a greater force back on your foot
Exerts an equal force back on your foot
Exerts a smaller force back on your foot
4
According to Newton's Law of Action-Reaction a book pushes down on a shelf and -
The shelf pushes up on the book
The floor pushes up on the shelf
The book pushes on adjacent books
5
If an object is at rest it will remain at rest until -
An unbalanced force is applied
Gravity quits acting upon the Earth
Balanced forces are applied
6
During a car accident a person without a seat belt could fly through the windshield due to -
Inertia
Balanced Forces
Gravity
Friction
7
Which of the following is the best example of velocity?
A basketball rolls 13 feet
Birds migrate south at 12 mph
A car travels 20 miles to the east
A dog runs 3 mph for 1 hour
8
Which would require the greatest force to accelerate?
Bicycle
Dump truck
Motorcycle
Cop car
9
Objects with smaller masses require _________ to accelerate than those with larger masses.
The same force
Less force
More force
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
equal and in the same direction
unequal and in the opposite direction
unequal and in the same direction
11
How do you calculate acceleration of a 25 kg object when 40 N of force are applied?
A = 25 kg + 40 N
A = 40 N/25 kg
A = 40 N x 25 kg
A = 25 kg/40 N
12
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
13
Which type of force must be applied in order to change an object's motion?
Frictional Force
Gravitational Force
Unbalanced Force
Balanced Force
14
An object in motion will stay in motion unless an unbalanced force is applied is the Law of
Action-Reaction
Inertia
Acceleration (F=MA)
15
Which best describes the motion of a car traveling 55 mph on a circular track.?
speed is contant and velocity is changing
speed and velocity are constant
speed is changing and velocity is constant
speed and velocity are both changing
