Honors Physics Unit 4: Forces and the Laws of Motion

The illustration shows the forces in Newtons (N) acting on three different blocks. Which boxes will move under these conditions?

• Blocks 1 and 2

• Blocks 2 and 3

• Blocks 1 and 3

• Blocks 1,2, and 3

The illustration shows the forces in Newtons (N) acting on each group. Which direction will the groups move under these conditions?

• To the right 2N

• To the left 2N

• To the right 22N

• To the left 10N

The illustration shows all the forces in Newtons (N) acting on a box. The sum of all the forces acting on the truck results in a force acting on the truck

• to the right with a strength of 40 Newtons.

• to the left with a strength of 40 Newtons.

• to the right with a strength of 60 Newtons.

• to the left with a strength of 60 Newtons

Students are investigating how mass affects the force needed to move an object. They attached a wooden block to a spring scale and placed a 10 g mass on top of the block and pulled it 50 cm across the table.What change(s) to their set-up would result in a larger force reading on the spring scale?

• Changing the mass to a larger amount.

• Changing the mass to a smaller amount

• Pulling the block 10cm across the table

• Using a different scale

The illustration below shows a cart different amounts of force being applied. What is the net force on the cart and in which direction is it?

• 5 N to the right

• 5 N to the left

• 8 N to the right

• 3 N to the left

A diagram of forces being applied to a box by four people is illustrated below. If the net force acting on the box is 10 N to the right, what is the magnitude of the force applied by the boy pulling to the left?

• 14N

• 21N

• 19N

• 11N

The illustration shows all the forces in Newtons (N) acting on a box. The sum of all the forces acting on the box results in a force acting on the box.

• to the right with a strength of 11 Newtons.

• to the left with a strength of 7 Newtons.

• to the left with a strength of 6 Newtons.

• to the right with a strength of 4 Newtons.

• Force

• Inertia

• Velocity

What causes a moving object to change direction?

• Acceleration

• Force

• Velocity

• Inertia
