Forces and Motion

Front

What is Newton's 1st law?

Back

Inertia: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd law?

Back

The harder I push this, the faster it will go: This law states that force equals mass times acceleration (F = m*a).

Front

What is friction?

Back

Friction is a force that acts opposite to the direction of motion.

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What happens when a force is applied to an object at rest?

Back

The object will start to move in the direction of the applied force.

Front

What is the relationship between mass and acceleration in Newton's 2nd law?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is inertia?

Back

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

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant speed.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
