NC 5.P.1.1/5.P.1.4 Newton’s Laws/ Predicting Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant speed and in a straight line unless acted upon by an unbalanced force.

Front

What is an unbalanced force?

Back

A force that causes an object to change its motion, such as its speed or direction.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion, slowing down or stopping moving objects.

Front

What is the difference between mass and weight?

Back

Mass is how much matter is in an object, while weight is the gravitational pull on that object.

Front

What happens when two equal forces act on an object in opposite directions?

Back

The forces cancel each other out, and the object does not move.

Front

What is the effect of gravity on falling objects?

Back

Gravity pulls objects toward the Earth, causing them to accelerate downward.

Front

How can you increase the speed of a rolling object?

Back

By reducing friction or increasing the slope of the ramp.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the role of a ramp in motion?

Back

A ramp can change the height and angle, affecting the speed and distance an object travels.
