A ball is moving upwards & to the left. A net force that points upwards & to the left must be acting on the ball.

• TRUE

• FALSE

A stationary object must have no forces acting on it.

• TRUE

• FALSE

An object's inertia causes it to come to a rest position.

• TRUE

• FALSE

An object that is not accelerating or decelerating must have zero net force acting on it.

• TRUE

• FALSE

NGSS.HS-PS2-1

When no net force is applied to a moving object, it still comes to rest because of its inertia.

• TRUE

• FALSE

When an object remains stationary, any forces acting on it must be balanced.

• TRUE

• FALSE

While you’re ice-skating with your friends, you push off from one end of the rink & slide forward. Based on Newton’s 1st law, what is true?

• You will lose your balance & fall over before you reach the middle of the ice rink.

• You will continue to slide across the ice until a force makes you stop or change direction.

• The force of gravity will make you keep your velocity until your friends make you stop.

• The size of your ice skates will determine how quickly or slowly you travel across the ice.

Your friend kicks a soccer ball, & it stops a few feet from you. What needs to happen to it in order for it to return to your friend?

• Force has to be applied to the ball.

• Friction has to be applied to the ball.

• Speed has to be applied to the ball.

• Inertia has to be applied to the ball.
