Which formula correctly calculates the distance (d) traveled by an object undergoing uniformly accelerated motion, given its initial velocity (u), acceleration (a), and time (t)?
d = ut
d = ut + 1/2 at^2
d = at^2
d = vt

8 m/s
12 m/s
18 m/s
24 m/s
A student claims that a rock dropped from a 55-meter cliff will hit the ground in 3.0 seconds. Using g = 9.8 m/s^2, which statement best evaluates this claim?
The student is correct; the calculated time is exactly 3.0 seconds.
The student is incorrect; the actual time is greater than 3.0 seconds.
The student is incorrect; the actual time is less than 3.0 seconds.
The student is incorrect; the mass of the rock is needed to calculate the time.
For an object in free fall near the Earth's surface (ignoring air resistance), which quantity remains constant?
Velocity
Speed
Acceleration
Displacement
A jogger runs at a constant speed of 4 m/s. A dog, starting from rest 10 meters behind, chases the jogger with a constant acceleration of 1 m/s^2. What allows the dog to eventually catch the jogger?
The jogger gets tired and slows down.
The dog's continuously increasing velocity allows it to close the gap.
The dog has a higher average speed from the start.
The distance between them is too short.
A boat is sailing east at 5 m/s. A passenger walks west across the deck at 2 m/s. What is the passenger's velocity relative to the water?
7 m/s west
3 m/s east
7 m/s east
3 m/s west
In projectile motion, which component of velocity is directly influenced by the force of gravity?
The horizontal component
The vertical component
Both components equally
Neither component
How does gravity affect the horizontal component of a projectile's velocity during its flight (ignoring air resistance)?
It causes the horizontal velocity to increase.
It causes the horizontal velocity to decrease.
It has no effect on the horizontal velocity.
It only affects horizontal velocity at the peak of the trajectory.
A kayaker can paddle at 3 m/s in still water. If they paddle directly across a river flowing at 4 m/s, what is the kayaker's resultant speed relative to the riverbank?
1 m/s
3 m/s
4 m/s
5 m/s
According to Newton's Third Law, if a computer sits on a desk, the reaction force to the Earth's gravitational pull on the computer is:

Which statement is the most complete description of Newton's First Law?
Force is equal to mass times acceleration.
An object will maintain its velocity unless acted upon by a net external force.
For every action, there is an equal and opposite reaction.
Energy cannot be created or destroyed.
