Physics Concepts

Front

A roller coaster is moving at 10 m/s at the top of a hill and 22 m/s at the bottom of the hill two seconds later.

Back

6 m/s²

Front

A ball is dropped from rest from a height of 6.0 meters above the ground. The ball falls freely and reaches the ground 1.1 seconds later.

Back

5.5 m/s

Front

The acceleration of the ball between 0 and 3 seconds is 1 m/s².

Back

This indicates that the speed of the ball increases by 1 meter per second every second during this time interval.

Front

A car approaching a red light is an example of negative acceleration.

Back

This means the car is slowing down as it approaches the stop.

Front

Unit of acceleration when speed is in meters per second and time is in seconds

Back

m/s²

Front

Knowing both speed and direction of an object's motion gives you the

Back

velocity of the object

Front

Newton's third law of motion states that when a hammer strikes and exerts force on a nail, the nail exerts an equal force back on the hammer.

Back

The nail exerts an equal force back on the hammer.

Front

Net force acting on the box is 4 N to the right.

Back

This indicates that the total force acting on the box results in a net movement to the right.

Front

Example of Newton's First Law of Motion: A bike stops moving when it hits a rock, but the rider flies over the handlebars.

Back

This illustrates the concept of inertia, where an object in motion stays in motion unless acted upon by an external force.

Front

Force required for a 20 kg object with 12 m/s² acceleration

Back

240 N
