Question

2) Rate at which the velocity changes; F/m

3) A push or pull; usually leads to an object changing its motion

4) Aligned with the rider’s back; not horizontal

5) Mathematically the tendency of a body to keep moving; product of mass and velocity

6) Effect of gravity’s pull on an object’s mass

7) Adjective meaning “active” or “in motion”; type of energy

9) Force of attraction between two bodies that have mass​

Answer 1

Explanation:

2) Acceleration

3) Force

4) Inertia of Motion

5) Momentum

6) Acceleration

7) Kinetic Energy

9) Gravitational force

Answer 2

The answers to the given questions are:

(2) Acceleration

- Acceleration is the rate of change of velocity.

- As F = ma

⇒ a = F/m

(3) Force

- A push or pull is a force.

- Generally, a body changes its motion due to the application of a force

(4) Vertical

- The back of a rider is in a vertical position.

(5) Momentum

- Momentum is the product of mass and velocity, i.e., p = mv.

(6) Weight

- Weight is the force (or effect) caused by gravity’s pull on an object’s mass.

(7) Kinetic Energy

- It is the energy possessed due to the motion of a body.

(9) Gravitational force

- Every body in the universe attracts every other body having mass.

- This is called gravitational force.
