What is the formula for distance ?

• VxT

• V/T

• DxT

What is a push or pull object ?

• Gravity

• Motion

• Force

• Friction

which of the following statements best describe inertia?

• A object will move faster as it gets heavier

• A object will continue to move at a constant speed unless acted by an unbalanced force

• An object will only stop moving if an external force acts on it

• An object will stay at rest or in motion unless a force changes its state

Which of the following is true when calculating work done by a force ?

• Work is the product of force and the displacement in the direction of the force

• Work is done only when the force acts perpendicular to the direction of motion

• The amount of work done depends on the magnitude of the force

• Work can never be negative

An object at rest will remain at rest, and an object in motion will remain in motion with the same speed and in the same direction unless acted upon by an unbalanced external force

• Newton 1st law

• Newton 3rd law

• Newton 2nd law

What is the formula for acceleration

• AxT

• F/V

• V/F

the acceleration of an object is directly related to the net force and inversely related to its mass

• Newton 3rd law ?

• Newton 1st

• Newton 2nd law

Which of the following is NOT a example of a simple machine

• Lever

• Electric motor

• Pulley

This means that if one object applies a force on another object, the second object applies a force of the same magnitude but in the opposite direction on the first object.

• Newton 3rd law

• Newton 2nd

• Newton 1st

What is an example of a scalar quantity

• Force

• Velocity

• Displacement

• Speed
