Physics Midterm TEST 2024

Front

Do two bodies have to be in physical contact to exert a force upon one another?

Back

No, the gravitational force is a field force and does not require physical contact to exert a force.

Front

What is the net force acting on an object moving steadily at constant velocity with a forward push of 3 N?

Back

The net force is zero.

Front

Does it take more force to accelerate a heavier object compared to a lighter object?

Back

True, it takes more force to accelerate an 18 wheel truck than a Toyota truck.

Front

What is the direction of acceleration when an object speeds up?

Back

Same as velocity.

Front

What is the force required to keep a rocket at constant velocity in outer space?

Back

Zero.

Front

Define gravitational force.

Back

A field force that acts at a distance without physical contact.

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 formula for calculating net force?

Back

Net Force = Mass x Acceleration.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

Acceleration is inversely proportional to mass when the net force is constant.
