semester 1 Review part 1

Front

What happens when two objects push off each other on a frictionless surface?

Back

Both objects will move in opposite directions, and their velocities will be inversely proportional to their masses.

Front

What is positive acceleration?

Back

Positive acceleration occurs when an object's velocity increases over time.

Front

What is the velocity of an object at its highest point in projectile motion?

Back

The velocity is zero at the highest point.

Front

What does it mean when forces are balanced?

Back

When forces are balanced, the net force acting on an object is zero, resulting in no change in motion.

Front

How do you calculate net force?

Back

Net force is calculated by subtracting opposing forces from each other.

Front

What is the formula for calculating net force when friction is involved?

Back

Net Force = Applied Force - Friction Force.

Front

What is inertia?

Back

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

Front

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

Back

According to Newton's second law, acceleration is inversely proportional to mass when the net force is constant.

Front

What is the definition of friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

What is the significance of a free-body diagram?

Back

A free-body diagram visually represents all the forces acting on an object, helping to analyze its motion.
