Question

question 6
identify the definition of friction.
a force that speeds up objects
a force that resists the motion of one object relative to another object
a force that slows down an object by pulling it downwards
a force that causes stretched objects to return back to their original shape
im not sure
question 7
select the type of force that tends to slow you down as youre swimming.
gravity
water resistance
applied force
elastic force
im not sure
question 8
select the type of force that causes a squashed or stretched object to return to its original shape.
friction
tension
elastic force
air resistance
im not sure
question 9
in most situations, many different types of forces are acting. when a soft, squishy ball falls and bounces on a concrete floor, identify which of these forces act.
air resistance
gravity
water resistance
elastic force
im not sure

Explanation:

• Question 6: Friction is defined as a force that resists the motion of one object relative to another object.
• Question 7: When swimming, the force that slows you down is water resistance.
• Question 8: The force that causes a squashed or stretched object to return to its original shape is elastic force.
• Question 9: When a soft, squishy ball falls and bounces on a concrete floor, air resistance (acts as the ball moves through the air), gravity (pulls the ball down), and elastic force (causes the ball to bounce back) act.

Answer:

• Question 6: A force that resists the motion of one object relative to another object.
• Question 7: Water resistance.
• Question 8: Elastic force.
• Question 9: Air resistance, Gravity, Elastic force.
