Acceleration
A ball is thrown straight upward. At the highest point, the ball’s:
Velocity is zero and acceleration is zero
Velocity is zero and acceleration is downward

The object’s velocity is constant
The object’s displacement is zero
A car travels east at constant speed. Which statement is correct?
The acceleration points east
The acceleration points west
The net force is zero
The velocity is zero
An object moves with a negative velocity and a positive acceleration. The object is:
Speeding up in the negative direction
Slowing down in the negative direction
Speeding up in the positive direction
Not moving
Which statement best describes acceleration?
It measures how fast an object is moving
It measures how far an object travels
It describes how velocity changes over time
It is the same as speed when direction is constant
A free-body diagram should include:
Only forces causing motion
Only forces in the direction of motion
All forces acting on the object
Only the net force
According to Newton’s First Law, an object will remain at rest or move at constant velocity if:
No forces act on it
The acceleration is zero
The net force is zero
Gravity is the only force acting
Which force always acts perpendicular to the surface of contact?
Friction
Normal force
Tension
Weight
A box is pushed to the right at constant speed across a rough floor. Which statement is true?
The applied force is greater than friction
The applied force equals friction
The net force points right
The box is accelerating
A student pushes on a wall with a force of 50 N. The wall does not move. Which statement is correct?
The wall exerts no force on the student
The student exerts a larger force than the wall
The wall exerts an equal force on the student
The forces cancel because the wall is stationary
A book rests on a table. Which statement is correct?
No forces act on the book
The normal force is larger than the weight

The net force points upward
A puck slides across frictionless ice at constant velocity. Which statement is true?
A net force is required to keep it moving
A net force acts opposite the motion

The puck must be accelerating
Two forces act on an object: 6 N to the right and 6 N to the left. What can be said about the object?
It must be at rest
It must be moving at constant velocity
Its acceleration is zero
No forces act on it
If the net force on an object increases while the mass stays the same, the acceleration:
Decreases
Increases
Stays the same
Becomes zero
Static friction differs from kinetic friction because static friction:
