For an investigation, a student measures the speed of a cart as it rolls down a ramp. The student then records data in the table below. Which of these best explains the student’s data?
The speed of the cart decreases as the cart rolls down the ramp because of friction between the cart and the ramp.
The speed of the cart increases as the cart rolls down the ramp because the force acting on the cart is greater than the force of gravity.
The speed of the cart increases as the cart rolls down the ramp because the forces acting on the cart are unbalanced.
The speed of the cart decreases as the cart rolls down the ramp because the forces acting on the cart are balanced.

At positions 1 and 4, the speeds are the same, but the velocities are different.
At positions 2 and 3, the accelerations are the same, but the velocities are different.
At positions 2 and 4, the velocities are the same, but the speeds are different.

Initial: Speed 8.0 m/s northeast, Velocity 8.0 m/s; Final: Speed 16.0 m/s northeast, Velocity 16.0 m/s.
Initial: Speed 8.0 m/s, Velocity 0.0 m/s² northeast; Final: Speed 16.0 m/s, Velocity 0.5 m/s² northeast.
Initial: Speed 8.0 m/s northeast, Velocity 8.0 m/s northeast; Final: Speed 16.0 m/s northeast, Velocity 16.0 m/s northeast.
A student investigates the motion of a toy vehicle. The student graphs 40 seconds of data from the investigation. Which statement best describes the motion of the toy vehicle during the first 30 seconds of the investigation?
The vehicle was traveling at a constant speed.
The vehicle was accelerating at a constant rate.
The speed of the vehicle was increasing.
The acceleration of the vehicle was increasing.
Which statement describes the meteor’s motion?
Its velocity was 7.8 km/s northward.
Its acceleration was 468 km/s².
Its speed was 468 km/s northward.
Its acceleration was 7.8 km/s².
Which statement best describes the cart?
The cart was stationary with a velocity of 0 m/s for the entire 7 seconds.
The cart was stationary except for a short burst of acceleration of 0.5 m/s².
The cart moved at a constant velocity of 0.5 m/s for the entire 7 seconds.
The cart accelerated at a constant rate of approximately 0.8 m/s².
Which of the following best describes the velocity of an object?

What is the difference between the velocity and the speed of an object?
Velocity is the change in distance over time, while speed is the change in velocity over time.
Velocity has a direction associated with it, while speed has no specific direction.
Velocity has no direction associated with it, while speed has a specific direction.
Velocity is the change in speed over time, while speed is the change in distance over time.
The three vehicles shown below are all traveling at a speed of 15 m/s, but only the pickup truck has a changing velocity. The pickup truck has a changing velocity because the pickup truck —
can accelerate faster than the other two vehicles
is traveling in the opposite direction from the other two vehicles
is traveling on a curve in the road
needs a large amount of force to move

When a coin is tossed in the air, it travels upward, gradually slows down, momentarily reaches zero speed, then moves back downward with increasing speed. Which statement best explains this change in the coin’s motion?
The force of gravity causes the coin to change its velocity.
The coin’s inertia decreases on the way up and increases on the way down.
The action-reaction force pair of gravity and the applied force cancel each other.
The coin remains in its state of upward motion until the force of friction acts upon it.
According to Newton’s first law, what happens to the steel ball just after the box stops?
Because of friction, the ball continues rolling forward at the same speed.
Because of friction, the ball rolls forward at an increased speed.
Because of inertia, the ball continues rolling forward at the same speed.
Because of inertia, the ball rolls forward at an increased speed.
