Question 5

Weight (definition and Measurement)

Answer 5

The force exerted on the body by gravity
Measured in Newtons

Question 6

Mass (Definition and Measurement)

Answer 6

The amount of matter an object is made up of
measured in Kgs

Question 7

Difference of Mass and Weight

Answer 7

Weight is recorded in Newtons and it is effected by gravity whereas mass is measured in Kgs and isn’t affected by gravity.

Question 8

Impulse (Definition and Measurement)

Answer 8

Impulse is the change of momentum in a body
Measured in Newtons Seconds

Question 9

Impulse equation

Answer 9

Impulse= force x time

Question 10

Momentum (Definition and equation)

Answer 10

The measure of the amount of motion an object has and its resistance to changing that motion
Momentum= Mass x Velocity

Question 11

Inertia

Answer 11

An Object will remain at rest or in constant motion unless acted upon by an external force.
More mass= more inertia
