REVISION TEST-GRADE 9(PHYSICS)

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

• The cart that weighs 5 kg.

• The cart that weighs 10 kg.

• The cart that weighs 12 kg.

• The cart that weighs 15 kg.

Morgan walks 10 miles South. Trevor walks 10 miles North in the same amount of time.  They have:

• Different average speeds
• Different velocities
• Same velocity
• Same motion

A ball is rolled at a velocity of 12 m/sec.  After 36 seconds, it comes to a stop.  What is the   acceleration of the ball?

• 3 m/s/s
• -3 m/s/s
• .33 m/s/s
• -.33 m/s/s

The balloon in this picture will be demonstrating which of Newton's Laws?

• Inertia
• F = ma
• Fourth Law
• Action-Reaction

Inertia is....

• for every action, there is an equal and opposite reaction
• larger objects take more force to move 
• an object in motion tends to stay in motion unless acted on by an opposite force
• a push that acts in the opposite direction and it slows down.

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia
• Newton's second law, the law of acceleration
• Newton's third law, the law of action reaction 
• The law of universal gravitation
