Physics Topic 1

Question 1

Force

Answer 1

strength or energy as an attribute of physical action or movement.

Question 2

Resultant Force

Answer 2

The resultant force. An object may have several different forces acting on it, which can have different strengths and directions. But they can be added together to give the resultant force. This is a single force that has the same effect on the object as all the individual forces acting together.

Question 3

Friction

Answer 3

the resistance that one surface or object encounters when moving over another.

Question 4

Uplift

Answer 4

lift (something) up; raise.

Question 5

Mass

Answer 5

a large body of matter with no definite shape

Question 6

Parallelogram of forces

Answer 6

The law of parallelogram of forces states that if two vectors acting on a particle at the same time be represented in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point their resultant vector is represented in magnitude and direction by the diagonal of the parallelogram drawn from …
