First Quarter Examination (Science 8)

An English scientist and mathematician famous for his discovery of the law of gravity also discovered the three laws of motion.

• Sir Isaac Newton

• Galileo Galilei

• Aristotle

A body at rest remains at rest and a body in motion remains in motion unless acted upon by an unbalanced force.

• Law of Inertia

• Law of Acceleration

• Law of Interaction

Force is directly proportional to the mass and acceleration

• Law of Inertia

• Law of Acceleration

• Law of Interaction

For every action there is an equal and opposite reaction.

• Law of Inertia

• Law of Acceleration

• Law of Interaction

It is a measurement of how quickly an object is changing speed.

• Inertia

• Acceleration

• Speed

The tendency of an object to resist changes in its state of motion.

• Inertia

• Acceleration

• Interaction

Push or pull (strength and energy)

• Force

• Velocity

• Acceleration

The rate of change of a position along a straight line with respect to time.

• Acceleration

• Velocity

• Speed

It is defined as the product of the net force acting on a body and the distance moved in the direction of the force.

• Work

• Power

• Energy

It is the rate at which work is done.

• Work

• Power

• Energy
