More mass is added to a wheelbarrow, and a larger force is required to move it - illustrates Newton's second law.
What is force?
An object's push or pull is seen as exerting a force. The interaction of the objects produces push and pull. You can also use words like stretch and squeeze to describe force.
The definition of force in physics is: The push or pull on a mass-containing item changes its velocity.
Newton’s second law of motion states that “Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration."
Hence more mass is added to a wheelbarrow, and a larger force is required to accelerate, i.e., move it.

the plane travels a distance of 1568 meters on the runway before takeoff. To find the distance traveled by the airplane before takeoff, we can use the following kinematic equation:
Where:
- d is the distance traveled.
- is the initial velocity, which is 0 m/s since the airplane starts from rest.
- a is the acceleration, which is 4.0 m/s².
- t is the time, which is 28.0 seconds.
Plugging these values into the equation:
Calculating this:
So, the plane travels a distance of 1568 meters on the runway before takeoff.

When the cart arrives at any place that's 1.0 meter higher than where it started, its potential energy will be
(9.8) · (its mass on kilograms) Joules .
Final answer:
Potential Energy is given by the formula mass x gravity x height. The starting height is irrelevant in its calculation. The potential energy depends on the mass of the object, gravity and the elevated height.
Explanation:
The potential energy of an object is calculated by the formula Potential Energy = mass x gravity x height. Whenever the height of an object increases, its potential energy will increase as well provided mass and the gravitational field (g) remain constant. Here, the starting height being 0.0 m is irrelevant to the calculation of potential energy at 1.0 m height. If the mass of the cart and the value of gravity (usually taken as 9.8 m/s2 on Earth's surface) are known, you can substitute those values into the formula to find the potential energy.
e.g. If the mass of the cart was 2 kg, the potential energy at a height of 1.0 m would be 2 kg x 9.8 m/s

x 1.0 m = 19.6 joules.

Answer: No.
Explanation: If an object moved to produce a vertical line on the velocity-time graph, it would mean that it would move at an infinite speed with no change in time. Nothing moves at an infinite speed; it is just not possible.
If you wanted to look at it through a calculus lens, acceleration is the derivative of velocity. You can't take the derivative of a vertical tangent line, so the acceleration wouldn't exist. This isn't possible if an object is moving; it has to have either constant acceleration or a non-zero acceleration.
