1st Semester Science Final Exam 2023

If you know the distance an object has traveled in a certain amount of time, you can determine

• the size of the object.
• the speed of the object.
• the location of the object.
• the velocity of the object.

When you know both the speed and the direction of an object’s motion, you know the

• average speed of the object.
• acceleration of the object.
• distance the object has traveled.
• velocity of the object.

Changing direction is an example of a kind of

• acceleration.
• speed.
• velocity.
• constant rate.

What part of a car causes negative acceleration?

• Steering wheel
• Gas pedal
• Brake pedal
• Blinker

The graph shown below provides information about the motion of a bicycle. When is the bicycle’s acceleration the greatest?

• At 0 seconds only
• From 0-3 seconds
• From 3-8 seconds
• From 8-9 seconds

The graph below shows the speed of an object during a 10 s time interval. In which of the following time intervals is the speed of the object staying constant?

• Between 0 s and 2 s
• Between 2 s and 5 s
• Between 5 s and 6 s
• Between 8 s and 10 s

Objects falling through air experience a type of friction called

• terminal velocity
• fluid friction.
• inertia.
• rolling friction.

The picture below shows the four major forces acting on an airplane in flight. What causes the force indicated by the X?

• gravity.
• free fall.
• acceleration.
• air resistance.

When two equal forces act on the same object in opposite directions, the net force is

• smaller than either force.
• equal to each of the forces.
• zero.
• greater than either force.
