Contact Forces Review - TG

Front

What type of force resists motion between two surfaces that are pressed together?

Back

Friction

Front

How can you describe a force?

Back

A push or pull

Front

In a game of tug-of-war, if both teams pull with equal force, what will happen according to Newton's third law?

Back

The rope will remain stationary.

Front

What does it mean when it takes more force to accelerate an object with more mass?

Back

This describes Newton's second law, the law of acceleration.

Front

If the forces on a rope are even, how will it move?

Back

The rope will not move because the forces are even.

Front

What is the definition of contact force?

Back

A force that acts at the point of contact between two objects.

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 unless acted upon by a net external force.

Front

What is the law of inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What does Newton's second law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma).
