Forces & Newton's Laws of Motion

The sum (total) of all forces acting on an object:

• Unbalanced Force

• Balanced Force

• Newtons

• Net Force

According to Newton’s second law of motion, force is equal to mass times ______________________.

• inertia

• weight

• acceleration

• direction

A force of 250 N is applied to an object that accelerates at a rate of 5 m/s².  What is the mass of the object? To solve this problem you must do - 

• 250 ÷ 5
• 5 ÷ 250
• 250 x 5

A skier needs to apply a force of 132 N to accelerate at a rate of 2 m/s². What is the mass of the skier? The answer to this question is most likely (HINT: Look at the units!!!) - 

• 66 N
• 66 m/s²
• 66 kg

What is the net force?

• 3 N

• 3 N, right

• 17 N, right

• 3 N, left

A lamp sitting on a table is demonstrating Newton's ___ Law.

• 1st

• 2nd

• 3rd

• 4th

Who wins the tug of war with what net force?

• The person on the left with 20 N
• The person on the left with 80 N
• The people on the right with 20 N
• The people on the right with 100 N

An unequal push/pull on an object that causes a change in motion:

• Unbalanced Force

• Push

• Balanced Force

• Inertia

The greater the mass of an object, the more force it will take to accelerate the object.

• Newton's 1st Law of Motion

• Newton's 2nd Law of Motion

• Newton's 3rd Law of Motion

Two equal forces acting in opposite directions on an object

• Inertia

• Balanced Force

• Push

• Unbalanced Force
