<em>A force is a vector that has both </em><em><u>magnitude</u></em><em> and direction.</em>

<em />

Explanation:

A force is defined as the amount of pull or push experienced by a body. The force acting on a body can bring about the change in the state of rest or motion of a body.

The physical quantities are broadly divided into two categories.

  • Scalar Quantities
  • Vector Quantities

The scalar quantities are the quantities that have only magnitude and do not require any direction for their representation whereas the vector quantities on the other hand are the quantities that require the magnitude as well as the direction for their representation.

The speed of a body is considered to be a scalar quantity whereas the velocity of the body considered as the vector because the velocity requires the direction along with the magnitude.

Similarly, the distance of a body is the length of a path covered by the body from the initial point. So, it is scalar but the displacement is the shortest distance between the initial and final point. SO, it is termed as vector as it has direction.

Similarly, the force acting on a body requires the magnitude as well the direction for the complete expression of the force.

Thus, <em>A force is a vector that has both </em><em><u>magnitude</u></em><em> and direction.</em>

a child is stationary on a swing. The child is given a push by a parent and the child starts swinging
Nesterboy [21]

Answer:

you havent given the full question

but im guessing momentum

momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity or the impetus gained by a moving object.

Explanation:

as the child is pushed, it gathers momentum as its weight allows it be pushed forward, and the velocity is the speed driven by the amount of force the parent pushes on the child whilst they are swinging. The momentum is the result of this action

the equation that links these factors together are

p = mv

p = momentum

m = mass

v = velocity

hope i got it right ._.

3) Calculate the kinetic energy of a 7 kg mass traveling at a velocity of 4 m/sec.
murzikaleks [220]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

Let's solve ~

Given terms :

  • Mass (m) = 7 kg

  • velocity (v)= 4 m/s

The formula to find kinetic Energy is ~

\boxed{ \boxed{ \sf{ \frac{1}{2}  m{v}^{2} }}}

Now, apply the formula according to given situation

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \dfrac{1}{2}  \times 7 \times ( {4)}^{2}

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \dfrac{1}{2}  \times 7 \times 16

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:7 \times 8

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:56 \:  \: joules

Therefore, the kinetic Energy of the car is 56 joules
