Question

You are required to make a concept map linking the following words together: - Acceleration - Angular - Biomechanics - Displacement - Distance - Equilibrium - Force - Friction - Impulse - Inertia - Joint Angle - Kinematics - Kinetics - Linear - Moment Arm - Momentum - Power - Rotation - Scalar - Speed - Time - Torque - Vector - Velocity - Work

Answer 1

Ans:

Displacement: shortest distance covered by a body in a definite direction

Distance: length of actual path covered by a moving object in a given time interval

Scalar: Physical quantities which have magnitude only and no direction

Vector: Physical quantities which have magnitude only and direction

Velocity = displacement / time

Speed = distance / time

Power: rate of doing work

Work: Product of force and displacement

Inertia: body opposes change in its initial state of rest or motion with uniform speed on a straight line

Force: when a body changes or tries to change the initial state is known as force

Momentum= mass x velocity

Impulse = force x time
