Front

Newton's 1st Law is also called the Law of ...

Back

Inertia: This law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.

Front

Hot things have ____________ thermal energy than cold things.

Back

more: Thermal energy is the total energy of all the particles in an object; hotter objects have more energy.

Front

What does a graph with a straight line represent?

Back

Constant Speed: A straight line on a distance-time graph indicates that the object is moving at a constant speed.

Front

What is happening at point D on a distance-time graph?

Back

Fast steady speed; moving away from the starting position: This indicates that the object is moving away from the starting point at a consistent speed.

Front

A dog runs on the sidewalk 9 mi/hr. What is this an example of?

Back

Speed: Speed is the distance traveled per unit of time, without regard to direction.

Front

What is the difference between speed and velocity?

Back

Velocity includes direction: While speed is how fast something is moving, velocity also tells us the direction of that movement.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time: This formula helps determine how fast an object is moving.

Front

What does a downward slope on a distance-time graph indicate?

Back

Returning to the starting position: A downward slope shows that the object is moving back towards the starting point.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion.
