According to Newton's first law of motion, what will happen to an object at rest or in motion in the absence of an unbalanced force?

• It will change direction

• It will speed up

• It will remain at rest or in motion in the same direction and speed

• It will slow down gradually

What is the acceleration due to gravity on Earth?

• 19.6 m/s²

• 9.8 m/s²

• 8.9 m/s²

• 6.7 m/s²

What is the difference between mass and weight?

• Mass is a measure of how much space an object occupies, while weight is how much matter it contains.

• Mass is a measure of how much matter an object contains, while weight is the force of gravity on that object.

• Mass is the force of gravity on an object, while weight is how much matter it contains.

• Mass and weight are the same thing.

What is the formula for mechanical advantage (MA) using input and output distance?

• MA = Resistance force (Fr) / Effort force (Fe)

• MA = Input distance / Output distance

• MA = Work output / Work input x 100%

• MA = Output distance (height) / Input distance (slope)
