Forces and Motion

To find the acceleration of an object using Newton's 2nd Law, you need to know its

• force and its size

• force and its mass

• force only

• weight and its mass

If two forces act on an object in the same direction, the net force is the

• difference of the two forces

• sum of the two forces

If two forces act on an object in opposite directions, the net force

• is the difference of the two forces

• is the sum of the forces

A _____ is a push or a pull on an object

• gravitational force

• force

• inertia

• friction

What metric unit is force expressed in?

• m/s2

• joules

• Kg

• N

Newton's 2nd Law explains the relationship between

• mass, force, and velocity

• mass, force, and acceleration

• mass, acceleration, and static force

• velocity, force, and air resistance

A force of 5 N pulls an object to the right, and a force of 3 N pulls to the left, what is the net force?

• 8 N right

• 8 N left

• 2 N right

• 2 N left

An object's resistance to change in its state of motion

• inertia

• friction

• force

• acceleration

More velocity will cause an object to have more

• gravity

• inertia

• momentum

• force

A ping pong ball and bowling ball are moving at the same velocity. Which of the two has more momentum? Why?

• The ping pong ball because it has less mass

• The bowling ball because it has more mass

• They have the same momentum because they have the same velocity
