Calculating Force, Mass, and Acceleration

Force is a -

• push or pull

• only a push

• only a pull

• none of the above

How much force is needed to accelerate a 3kg skateboard at 5m/s^2. 

• 8N
• 1.6N
• 0.6N
• 15N

How much force is needed to accelerate a 25kg bowling ball at 2m/s². 

• 50N
• 5N
• 12.5N
• 100N

If a 2kg bird is pushed by the wind with a force of 2N, how fast does the bird accelerate?

• 1 m
• 2 m/s²
• 4m/s²
• 1 m/s²

Newton's law of motion describes the relationship of force, mass, and acceleration. Write the equation.

• M=F/A
• F=MA
• A= F/M
• All of the above

The classes are playing tug of war. Barsoum’s room pulls to the left with a force of 45 N. Coach Camacho's room pulls to the right with a force of 50 N. What is the net force? And who won?

• 5N right. Coach Comacho's Class won.
• 5N Left. Barson's class won. 
• 95N and Coach Comacho's class won. 
• 95N and Barson's class won.

Which is an unbalance force?

• A book sitting on a desk.
• A ball moving in a constant speed in the same direction. 
• While doing a mannequin challenge Jose suddenly falls over when a bug lands on his nose. 
• Every student in class is sitting perfectly still at their desks.
