Today we will be able to EXPLAIN how equal and unequal
forces acting on an object cause patterns of motion and
transfer of energy

DOL: Given problems, SW correctly explain how equal and
unequal forces acting on an object cause patterns
of motion and transfer of energy in at least 4 of 5
questions.

Topic 3: Force and Motion

Multiple Choice

Two people are pushing on opposite sides of a box with equal force. What is an equal force?

• A force that is equal in size and does not change motion

• A force that causes a change in motion

• A push or pull which may change an object's motion

• A force that causes objects with mass to attract to one another

• A change in a position or object

• Change in motion, speed up, slow down, or change direction

• A force equal in size but opposite in direction

• A push or pull that causes an object to move

What is Friction?

• A type of energy that enhances motion.

• A force equal in size but opposite in direction

• A measurement of speed between two objects.

• Friction is a force that resists motion between two surfaces in contact.

What is Gravity?

• An act or process of changing position or location

• A force that causes objects to attract to each other

• The force that resists the motion of an object

• A force that moves an object towards you

Gravity as a Force

A force that pulls things
toward each other. It's what
makes things fall to the
ground when you drop them,
and it’s the reason we stay on
Earth instead of floating into
space!

Friction as a Force

A force that happens when two things rub against each other. It slows things down or stops them from moving

Multiple Choice

Two children are playing tug-of-war. One child pulls harder than the other, and the rope moves toward the stronger child. What causes the rope to move toward the stronger child in terms of energy transfer?

• Energy stays with the stronger child only.

• The unbalanced force of the stronger child’s pull transfers energy, causing the rope to move toward that child.

• Energy is transferred equally on both sides, but the stronger child wins

• Energy transfers only to the child’s hands, pulling the rope.

Multiple Choice

A wagon is pushed and begins to move. As the wagon moves, it slows and comes to a stop. The wagon and the direction in which it is pushed are shown in the image. What force causes the wagon to stop?

• The force of gravity which is acting in the same direction as the arrow.

  
  

• The force of friction which is acting in the same direction as the arrow.

  
  

• The force of gravity which is acting in the opposite direction of the arrow.

  
  

• The force of friction which is acting in the opposite direction of the arrow.

  
  

Multiple Choice

In Ms. Thompson's fifth-grade science class, students are learning about how different forces act on objects in nature and how these forces can cause motion or transfer energy. The students go on a nature walk and observe a leaf being blown by the wind, slowing down as it lands on the ground covered with grass.

As the students observe the leaf slowing down and eventually stopping when it lands on the grassy ground, which force is most likely causing this change in motion?

• Friction

• Gravity

• Applied Force

• Air Resistance
