8.6 C Physics STAAR (Newton´s Laws)

Which answer choice best explains why tractor trailers take more time to speed up & slow down than regular cars?

• Tractor trailers have less mass and require less force to move.
• Tractor trailers have more mass and require more force to move.
• Tractor trailers have less mass and require more force to move.
• Tractor trailers have more mass and require less force to move. 

If a force of 50 Newton's was applied to an object with a mass of 500 grams, what will the object's acceleration be?

• 10 m/s^2
• .1 m/s^2
• 100 m/s^2
• 1 m/s^2

A five kilogram object attained a velocity of 5 m/s one second after a force was applied. In Newtons, what was the strength of the force?

• 10 Newtons
• 5 Newtons
• 25 Newtons
• 20 Newtons

If an object was accelerating at 10 m/s², and a force of 10 newtons was required to accelerate it, what was the object's mass?

• 1 kilogram
• 10 kilograms
• 2 kilograms
• 5 kilograms

If a 10 kilogram object accelerates suddenly at 15 m/s², how much force was applied to the object?

• 150 Newtons
• 15 Newtons
• 150 kilograms
• 100 kilograms

As the acceleration of an object increases, what happens to the force of the object? 

• force increases
• force decreases
• force remain the same
• mass increases

True or False.  An increase in mass will result in an increase in the acceleration?

• True
• False

The masses of four objects are given in this table. If all objects are struck with the same amount of force, which one will have the greatest acceleration?

• Object 1
• Object 2
• Object 3
• Object 4

A force of 90N is applied to each cart below, which one will accelerate the fastest?

• Cart 1
• Cart 2
• Cart 3 
• Cart 4

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.
